More efficient and less costly solar cells.

Three Swiss organisations launched a European research project with nine international partners that will develop a new generation of photovoltaic cells.

These new cells will use perovskite*-based photovoltaic technology, which could provide greater efficiency at a lower cost than is possible today. CSEM is coordinating this project, named CHEOPS, with a budget of €5 million.

Perovskite-based photovoltaic technology draws upon a new category of materials characterised by a unique crystalline structure. It offers promising possibilities in terms of lowering manufacturing costs and increasing efficiency. Currently, this technology is used only for small surfaces produced in the laboratory, and offers a limited life span.

CHEOPS aims to advance this innovative technology for the benefit of the economy and society. The partners involved in the project will seek to improve current technology by developing a tandem cell using a perovskite top cell and a standard silicon bottom cell.

CHEOPS is co-funded by the European research and innovation programme Horizon 2020. The project officially began in February 2016 and will end in January 2019. It involves 12 partners from industry and academia from seven European countries, and has a budget of €5 million. CHEOPS is coordinated by CSEM.
