Ionic liquid-based perovskite solar cell with 22.86% efficiency
A Swiss-Japanese research group has used ionic liquids doping to improve the efficiency and stability of perovskite solar cells. Their champion device showed an open-circuit voltage of 1.16 V, a short-circuit current of 24.03 (mA cm−2), and a fill factor of 0.818. It was also able to retain around 95% of its initial efficiency after 1,000 hours of operation.
Japan’s first vertical agrivoltaic project
The facility was built with heterojunction modules and mounting systems provided by German companies Luxor Solar and Next2Sun, respectively. The distance between the panel rows ranges from 8 to 10 meters and the agricultural surface within the rows will be utilized by local livestock farmers as pasture.
