摘要

High efficiency organic–inorganic hybrid perovskite solar cells(PSC) have experienced rapid development and attracted significant attention in recent years.The crystal growth process as an important factor will significantly influence the quality of perovskite films and the device performance, which usually requires thermal annealing for 10 or more minutes.Herein, we demonstrate a new method to get highly crystallization of perovskite film by current annealing(CA) for just 5 seconds.The fast crystallization process introduced by large current annealing effectively increased the grain size and crystallinity of perovskite, thus leading to higher Voc and FF.An average PCE of 17.02% was obtained, which is higher than that of the devices with thermal annealing process(16.05%).Besides, our current annealing process has less energy loss and time consumption, which is also friendly to the industrial mass production.
