Progress of Perovskite Solar Modules

Perovskite solar cells (PSCs) reached 25.5% of certified power conversion efficiency (PCE) in 2020. A remarkable PCE of PSCs has urged scalable technologies to grow for manufacturing modules. Therefore, scalable technology is rapidly developing though the performance of perovskite solar modules (PSMs) is still far behind that of PSCs. Herein, the recent progress in scalable technologies is reviewed with addressing important parameters in each process. In addition, the performance measurement protocols for PSMs are specifically discussed based on International Electrotechnical Commission to be prepared from the industrial point of view. Finally, the environmental hazard impact by accidental lead leakage and the introduction of green solvent to replace of current toxic solvent are described.
