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.
Power Roll developing 12.8%-efficient back-contact perovskite solar devices
Researchers from the U.K.’s University of Sheffield and Power Roll, a perovskite solar PV technology company, have achieved 12.8% power conversion efficiency in indium-free devices based on novel back-contact process. A slot-die coating process was demonstrated, compatible with roll-to-roll manufacturing.
