Company Profile (EMPA)

EMPA logo
EMPA (Swiss Federal Laboratories for Material Testing and Research)is an interdisciplinary research and services institution to meet the requirements of industry and the needs of our society, and it links together applications-oriented research and the practical implementation of new ideas. The Laboratory for Thin Films and Photovoltaics has recently relocated from ETH Zurich. Dr. Ayodhya N. Tiwari has been leading the PV group involved in the R&D of thin film solar cells based on compound semiconductors. The group has made several important contributions in the field of CIGS and CdTe thin film solar cells on glass and flexible substrates including the achievement of 14.1% efficiency (highest efficiency record for any type of solar cell grown on polymer film) flexible CIGS solar cell on polymide film and 11.4% record high efficiency for flexible CdTe solar cells. Other innovative developments include flexible CIGS solar cells on low cost aluminium foil, application of simple and safe non-vacuum CIGS deposition processes, high efficiency multi-junction (tandem) solar cells based on CIGS, CdTe, and Dye sensitized solar cells. The lab is involved in collaborative and industrial research, and technology transfer to start-up companies.
