Perovskite solar cells have been developing very rapidly and are already in the phase of mass production. Although its power conversion efficiency has been rapidly increasing, more fundamental research is needed for further development in order to distribute reliable products to the market. Especially, fabrication control of perovskite crystal is important because the reproducibility of the device performance is important issue for the perovskite solar cells. We have been focusing on vacuum deposition, aiming for precise control of perovskite fabrication. We also conducted real-time X-ray diffraction analysis using the synchrotron facility SPring-8 to investigate the dynamics of the perovskite crystallization process from the viewpoint of both solution process and vacuum deposition process.
