Bruno Ehrler is a physicist and materials scientist whose research centers on perovskite semiconductors, hybrid solar cells, and neuromorphic devices.[1] He leads the Hybrid Solar Cells group at AMOLF and has been appointed as the next director of the instittue effective 1 January 2026.[2] Since 2020 he has been an honorary professor at the University of Groningen.[1][3]
After his doctorate, Ehrler joined the Cambridge Optoelectronics Group as a postdoctoral researcher with Richard Friend, working on quantum dots, doped metal oxides, and singlet fission photovoltaics.[1] He was Trevelyan Research Fellow at Selwyn College, Cambridge from 2013 to 2014.[1]
In 2014 he moved to AMOLF as Group Leader of the Hybrid Solar Cells group.[1] He became head of the LMPV – Sustainable Energy Materials Department in 2024,[1] and in August 2025 was named the next director of AMOLF, to take office on 1 January 2026.[2][4]
Research
Ehrler's research focuses on the physics and chemistry of perovskite semiconductors. He has worked on how ionic migration affects device stability and efficiency, and developing spectroscopic and simulation tools.[5] His group found that mechanical strain can control ion mobility, opening new ways for improving perovskite solar cell performance.[5] In addition to photovoltaics, Ehrler's group has worked on the use of perovskites in neuromorphic computing, creating artificial synapses and neurons with very low energy consumption.[5][6]
Policy roles
Ehrler is active in Dutch and European research policy, serving as Vice-Chair of the Netherlands Energy Research Alliance (NERA) and Program Director of SolarLab.[2][1] He was part of founding the national research programs SolarNL and MaterialenNL.[5]
Awards and honours
2025 – KNCV Gold Medal (Royal Netherlands Chemical Society)[5]
