Three of CHEOPS’ partners have tackled the task to optimize the material, processes and encapsulation to achieve the desired high-efficiency 5x5 cm² perovskite modules: CHOSE (Università degli Studi di Roma 'Tor Vergata'), CSEM (Centre Suisse d’Électronique et de Microtechnique) and UOXF (University of Oxford). They have all succeeded to produce such modules with different architectures (mesoscopic and planar), with different techniques (e.g. spin and blade coating) and different materials. The table below shows their interim results.
In the coming year, CHEOPS will select the most promising formulations and techniques to further upscale the modules. The goal is to present a 10x10 cm² demonstrator in January 2018 (other project milestones are documented in our online timeline).
