The economy of Ukraine is an emerging,lower-middle income,mixed economy located in Eastern Europe. It grew rapidly from 2000 until 2008 when the Great Recession began worldwide and reached Ukraine. The economy recovered in 2010 and continued improving until 2013. From 2014 to 2015,the Ukrainian economy suffered a severe downturn,with GDP in 2015 being slightly above half of its value in 2013. In 2016,the economy again started to grow. By 2018,the Ukrainian economy was growing rapidly,and reached almost 80% of its size in 2008.
Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect,a phenomenon studied in physics,photochemistry,and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors.
Copper indium gallium (di)selenide (CIGS) is a I-III-VI2 semiconductor material composed of copper,indium,gallium,and selenium. The material is a solid solution of copper indium selenide (often abbreviated "CIS") and copper gallium selenide. It has a chemical formula of CuIn1−xGaxSe2,where the value of x can vary from 0 (pure copper indium selenide) to 1 (pure copper gallium selenide). CIGS is a tetrahedrally bonded semiconductor,with the chalcopyrite crystal structure,and a bandgap varying continuously with x from about 1.0 eV (for copper indium selenide) to about 1.7 eV (for copper gallium selenide).
Nanosolar was a developer of solar power technology. Based in San Jose,CA,Nanosolar developed and briefly commercialized a low-cost printable solar cell manufacturing process. The company started selling thin-film CIGS panels mid-December 2007,and planned to sell them at 99 cents per watt,much below the market at the time. However,prices for solar panels made of crystalline silicon declined significantly during the following years,reducing most of Nanosolar's cost advantage. By February 2013 Nanosolar had laid off 75% of its work force. Nanosolar began auctioning off its equipment in August 2013. Co-Founder of Nanosolar Martin Roscheisen stated on his personal blog that nanosolar "ultimately failed commercially." and that he would not enter this industry again because of slow-development cycle,complex production problems and the impact of cheap Chinese solar power production. Nanosolar ultimately produced less than 50 MW of solar power capacity despite having raised more than $400 million in investment.
First Solar,Inc. is an American manufacturer of solar panels,and a provider of utility-scale PV power plants and supporting services that include finance,construction,maintenance and end-of-life panel recycling. First Solar uses rigid thin-film modules for its solar panels,and produces CdTe panels using cadmium telluride (CdTe) as a semiconductor. The company was founded in 1990 by inventor Harold McMaster as Solar Cells,Inc. and the Florida Corporation in 1993 with JD Polk. In 1999 it was purchased by True North Partners,LLC,who rebranded it as First Solar,Inc.
Ensuring adequate energy supply to sustain economic growth has been a core concern of the Chinese government since 1949. The country is the world's largest emitter of greenhouse gases,and coal in China is a major cause of global warming. However,from 2010 to 2015 China reduced energy consumption per unit of GDP by 18%,and CO2 emissions per unit of GDP by 20%. On a per-capita basis,it was the world's 51st largest emitter of greenhouse gases in 2016. China is also the world's largest renewable energy producer. China is the largest producer of hydroelectricity,solar power and wind power in the world. The energy policy of China is connected to its industrial policy. The goals of China's industrial policy dictate its energy needs.
Industry is 39.4% of China's gross domestic product (GDP) in 2022. In 2007,industry contributed 46.7 percent of GDP in 2010 and occupied 27 percent of the workforce. In 2015,the manufacturing industrial sectors contributed to 40% of China's GDP. The manufacturing sector produced 44.1 percent of GDP in 2004 and accounted for 11.3 percent of total employment in 2006.
HelioVolt Corporation was a privately held solar energy company based in Austin,Texas that suspended operations in 2014. The company manufactured photovoltaic (PV) solar modules using a thin film semiconductor process based on copper indium gallium selenide (CIGS) to produce CIGS solar cells. HelioVolt manufactured these thin film modules for commercial rooftop,utility-scale ground mount,residential,building-integrated photovoltaics (BIPV) and custom installations. The company raised over $230 million in investments,including over $80 million by SK Group.
MiaSolé is an American solar energy company selling copper indium gallium selenide (CIGS) thin-film photovoltaic products. MiaSolé's manufacturing process lays CIGS on a flexible stainless steel substrate. MiaSoléproduces all layers of photovoltaic material in a continuous sputtering process.
China is the largest market in the world for both photovoltaics and solar thermal energy. China's photovoltaic industry began by making panels for satellites,and transitioned to the manufacture of domestic panels in the late 1990s. After substantial government incentives were introduced in 2011,China's solar power market grew dramatically:the country became the world's leading installer of photovoltaics in 2013. China surpassed Germany as the world's largest producer of photovoltaic energy in 2015,and became the first country to have over 100 GW of total installed photovoltaic capacity in 2017.
SunEdison,Inc. is a renewable energy company headquartered in the U.S. In addition to developing,building,owning,and operating solar power plants and wind energy plants,it also manufactures high purity polysilicon,monocrystalline silicon ingots,silicon wafers,solar modules,solar energy systems,and solar module racking systems. Originally a silicon-wafer manufacturer established in 1959 as the Monsanto Electronic Materials Company,the company was sold by Monsanto in 1989.
Global Solar Energy is a US-based manufacturer of CIGS solar cells,a thin-film based photovoltaic technology,with manufacturing operations in Tucson,Arizona,United States,and Berlin,Germany. In 2013,it was bought by Chinese renewable energy company Hanergy.
Ascent Solar Technologies,Inc. is a publicly traded photovoltaic (PV) company located in Thornton,Colorado. Its primary product is a flexible CIGS solar cell on a plastic substrate.
Thin-film solar cells are made by depositing one or more thin layers of photovoltaic material onto a substrate,such as glass,plastic or metal. Thin-film solar cells are typically a few nanometers (nm) to a few microns (µm) thick–much thinner than the wafers used in conventional crystalline silicon (c-Si) based solar cells,which can be up to 200 µm thick. Thin-film solar cells are commercially used in several technologies,including cadmium telluride (CdTe),copper indium gallium diselenide (CIGS),and amorphous thin-film silicon.
Between 1992 and 2022,the worldwide usage of photovoltaics (PV) increased exponentially. During this period,it evolved from a niche market of small-scale applications to a mainstream electricity source.
A copper indium gallium selenide solar cell is a thin-film solar cell used to convert sunlight into electric power. It is manufactured by depositing a thin layer of copper indium gallium selenide solution on glass or plastic backing,along with electrodes on the front and back to collect current. Because the material has a high absorption coefficient and strongly absorbs sunlight,a much thinner film is required than of other semiconductor materials.
