The Photovoltaics-Laboratory (PV-Lab) of the Institute of Microengineering (IMT-EPFL), founded in 1984 by Prof. Arvind Shah and headed by Prof. Christophe Ballif since 2004, has pioneered several new processes for the preparation of thin-film silicon, such as the introduction of very high frequency (VHF) plasma deposition and microcrystalline silicon as an efficient photovoltaic material, and simple processing of heterojunction crystalline cells. Current activities of the laboratory cover a broad spectrum, ranging from fundamental research to industrial technology transfer. The lab masters processes of device fabrication for a wide variety of transparent conductive oxides, thin-film solar cells and high-efficiency crystalline silicon solar cells. It also has expertise for specialty detectors. It has full facilities for packaging of PV products. It has been designated as a center of national importance by the Swiss Federal Office for Energy.
PV-lab is a founding partner of the CSEM PV-center, which started operation in 2013 with a focus on technology transfer, and industrialisation of technologies.
