History

Fraunhofer ISE was founded in 1981 by Adolf Goetzberger in Freiburg, Germany. It was the first non-university establishment for applied solar energy research in Europe. The first areas of focus were the fluorescent collector FLUKO, transparent insulation and the initial steps towards high efficiency silicon and III-V solar cells, silicon thin film solar cells and material research. [3]

Already in 1983, the first fully electronic so-called "ISE inverter" was developed for use in autonomous photovoltaic systems.[ citation needed ] In 1986, the first serial product using fluorescent collectors as a power supply was produced.[ citation needed ] Within the PV small device program, numerous other successful products were developed. When the clean room was put into operation in 1989, the production of high efficiency solar cells began. In 1998, selective solar absorber coatings, which were developed at Fraunhofer ISE for solar thermal collectors, were put into industrial-scale production.[ citation needed ]

In 2011 Fraunhofer ISE celebrated its 30th anniversary. Since its founding, the scientists have received many prestigious prizes and awards for their research results in the field.[ which? ]

Research and development

The solar energy research at Fraunhofer ISE establishes the technical prerequisites for an efficient and environmentally friendly energy supply for industrial as well as threshold and developing countries. The institute is committed to moving away from fossil fuels and nuclear power and moving towards a 100% renewable energy supply with the aim of providing affordable solutions for the energy transformation.

To this purpose, the institute develops materials, components, systems and processes for basic research and beyond. The areas of expertise include the development of production techniques and prototypes, setting up and monitoring demonstration systems and operating indoor and outdoor testing and calibration centers. [2]

The various areas of research at Fraunhofer ISE are categorized into the following business areas:

Energy Efficient Buildings
At Fraunhofer ISE, energy-efficient buildings are one of the main areas of research. Teaming up with architects, expert planners and the industry, the researchers at Fraunhofer ISE optimize the performance of existing building and develop the buildings of tomorrow with consideration to the economic aspects, the energy efficiency and the user comfort. Through its involvement in the International Energy Agency (IEA), the Institute contributes in the establishment of the international boundary conditions for the realization of these concepts. In this business area, many disciplines come together: from material research and coating development through to component and system development and finally the required tests. [2]

Applied Optics and functional Surfaces
Solar energy systems convert solar radiation incident on the earth into thermal, electrical or chemical energy. In order to better transmit, reflect, absorb, filter, redirect or concentrate the incoming radiation, Fraunhofer ISE develops optical components and systems. This business area serves as an interdisciplinary field and serves many areas of solar technology: windows and facades, solar thermal collectors, concentrator systems for photovoltaics and solar power plants as well as photovoltaic module technology. [2]

Solar Thermal Systems
This business area covers the markets of low and high temperature applications. Solar thermal collectors and collector systems with flat or evacuated tube collectors find numerous applications in the practice. These include process water and solar heating systems, cooling and ventilation systems and sea water desalination systems. Also façade-integrated collectors are implemented. With linear concentrating collectors, operating temperatures from 150 °C to over 400 °C are achieved. Both trough and parabolic collectors are not only used for solar thermal power production in large power plants, but also in simpler and more cost-effective plants for the production of process heat, process steam and driving heat for absorption chillers. [2]

Silicon Photovoltaics
Especially due to the market introduction programs in Japan and Germany, the role of photovoltaics is gaining more and more on importance. More than 85% of the solar cells produced worldwide are based on crystalline silicon. The price-performance ratio, long-term stability and the cost-reduction potential indicate that this top performer in the terrestrial photovoltaic market will retain its place as market leader longer than just the next decade. Fraunhofer ISE's expertise ranges over the entire value chain of crystalline silicon photovoltaics, starting from material development and crystallization, through to solar cell processing and photovoltaic module technology. [2]

Photovoltaic Modules and Systems
Module technology converts solar cells into a robust product for reliable operation in PV power plants. Fraunhofer ISE supports the product development concentrating on increasing efficiencies, reducing costs and achieving the highest reliability. Over and above, the Institute offers its services for quality assurance of modules and power plants. [2]

Alternative Photovoltaic Technologies
In addition to silicon photovoltaics, the solar cell research at Fraunhofer ISE also extends to other photovoltaic technologies: With III-V based semiconductors like gallium indium phosphide, aluminum gallium arsenide or gallium arsenide, the highest efficiencies can be reached today. The technology of the dye solar cells has developed well beyond the laboratory stage and organic solar cells are attractive especially due to the expected low manufacturing costs. [2]

Renewable Power Supply
The construction of grid-connected systems is the largest market for the photovoltaic branch today. The Institute provides consultancy services for system planning, characterizes solar modules and carries out the technical analysis and performance testing of photovoltaic systems. [2]

Off-grid power supplies also are a focus of the ongoing research at the institute. People living in remote rural areas, the countless number of telecommunication systems, environmental measurement technology as well as portable electronic devices require an autonomous power supply, independent of the grid. Fraunhofer ISE develops renewable energy systems for this purpose. [2]

Fraunhofer ISE also performs research in the area of power electronics and controls. This includes inverter development and testing in a modern power electronics laboratory as well as research in the field of energy management including smart metering and smart grids. [2]

In future, vehicles will run partly or completely on electricity and draw their energy from the grid (electric and plug-in). Fraunhofer ISE is working at the interface between the vehicles and the grid on concepts for an environmentally acceptable power supply and the optimal integration of the vehicles into the electricity grid, including metering and billing systems. [2]

Hydrogen Technology
In a fuel cell, hydrogen reacts with oxygen and sets useful energy free in the form of electricity and heat. Since hydrogen does not exist in its pure form in nature, it must be produced from one of its many chemical compounds. At Fraunhofer ISE in the area of hydrogen technology, the research focuses on innovative technologies for hydrogen generation and on processes for the highly efficient conversion of hydrogen into electricity and heat using the most modern equipment. Together with partners from industry and science, components and complete fuel cell systems are developed for autonomous, portable as well as mobile applications. [1] [2] [4]

A solar cell, or photovoltaic cell, is an electronic device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon. It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Individual solar cell devices are often the electrical building blocks of photovoltaic modules, known colloquially as solar panels. The common single junction silicon solar cell can produce a maximum open-circuit voltage of approximately 0.5 to 0.6 volts.

<span class="mw-page-title-main">Solar power</span> Conversion of energy from sunlight into electricity

Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Photovoltaic cells convert light into an electric current using the photovoltaic effect. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine.

A photovoltaic system, also PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics. It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and other electrical accessories to set up a working system. It may also use a solar tracking system to improve the system's overall performance and include an integrated battery.

<span class="mw-page-title-main">Photovoltaic thermal hybrid solar collector</span>

Photovoltaic thermal collectors, typically abbreviated as PVT collectors and also known as hybrid solar collectors, photovoltaic thermal solar collectors, PV/T collectors or solar cogeneration systems, are power generation technologies that convert solar radiation into usable thermal and electrical energy. PVT collectors combine photovoltaic solar cells, which convert sunlight into electricity, with a solar thermal collector, which transfers the otherwise unused waste heat from the PV module to a heat transfer fluid. By combining electricity and heat generation within the same component, these technologies can reach a higher overall efficiency than solar photovoltaic (PV) or solar thermal (T) alone.

<span class="mw-page-title-main">Concentrator photovoltaics</span> Use of mirror or lens assemblies to generate current from multi-junction solar cells

Concentrator photovoltaics (CPV) is a photovoltaic technology that generates electricity from sunlight. Unlike conventional photovoltaic systems, it uses lenses or curved mirrors to focus sunlight onto small, highly efficient, multi-junction (MJ) solar cells. In addition, CPV systems often use solar trackers and sometimes a cooling system to further increase their efficiency.

<span class="mw-page-title-main">Solar cell research</span> Research in the field of photovoltaics

There are currently many research groups active in the field of photovoltaics in universities and research institutions around the world. This research can be categorized into three areas: making current technology solar cells cheaper and/or more efficient to effectively compete with other energy sources; developing new technologies based on new solar cell architectural designs; and developing new materials to serve as more efficient energy converters from light energy into electric current or light absorbers and charge carriers.

Amonix, Inc. is a solar power system developer based in Seal Beach, California. The company manufactures concentrator photovoltaic (CPV) products designed for installation in sunny and dry climates. CPV products convert sunlight into electrical energy in the same way that conventional solar photovoltaic technology does, except that they use optics to focus the solar radiation before the light is absorbed by solar cells. According to a comparative study of energy production of solar technologies, CPV systems require no water for energy production and produce more energy per megawatt (MW) installed than traditional PV systems. Amonix has nearly 70 megawatts of CPV solar power systems deployed globally, including Southwestern U.S. and Spain. In May 2012, the Alamosa Solar Generating project, owned and operated by Cogentrix Energy, began commercial operation. This is the largest CPV power plant in the world and is expected to produce enough clean renewable energy per year to power more than 6,500 homes and will avoid the emissions of over 43,000 metric tons of carbon dioxide per year. The Alamosa Solar Generating Project is supported by a power purchase agreement (PPA), which is a long-term agreement to sell the power it will generate. Under the project's PPA, the Public Service Company of Colorado will buy the power generated by the solar facility for the next 20 years. In July 2012, Amonix set the world record for photovoltaic module efficiency at 33.5% under nominal operating conditions, verified by the National Renewable Energy Laboratory. In April 2013, Amonix broke the record set in July 2012, demonstrating photovoltaic module efficiency at 34.9% under normal concentrator standard operating conditions, also verified by the National Renewable Energy Laboratory. In August 2013, Amonix announced it had achieved a 35.9% photovoltaic module efficiency rating under concentrator standard test conditions (CSTC) as calculated by NREL. In June, 2014, the assets of Amonix were acquired by Arzon Solar, LLC for the purpose of continued development of CPV technology and products.
