Chinese scientists build 20.3%-efficient mini inverted perovskite solar modules via slot die coating A team led by University of Electronic Science and Technology of China (UESTC) has found that pyrrodiazole as an additive in formamidinium iodide (FAI)-based inverted perovskite solar enables larger area devices made with industry-compatible slot die coating. Modules made using the technology achieved 20.3% certified power conversion efficiency and retained 94% of initial efficiency after 1,000 h in standard testing.
