Perovskite semiconductors have generated great interest in photovoltaics research as they promise to enable the production of solar cells that are at the same time extremely efficient and very low cost. The main goal of the CHEOPS project is to explore this potential by developing materials and production processes for both upscaling the technology and producing solar cells in a tandem configuration. This implies that a perovskite cell is joined with a ‘conventional’ crystalline silicon cell. Such tandem cells are currently expected to have the best chances to succeed on the photovoltaics market because their production could most likely be integrated into existing manufacturing processes and equipment. In order to achieve its ambitious goals, CHEOPS unites a team of European leaders in academic and industrial perovskite research. The CHEOPS project results are presented in a number of prominent scientific journals including Nature Materials.
In summary, CHEOPS will decisively advance the potentially game-changing perovskite technology towards the market and will thus help to face the energy challenge in Europe and beyond.
