Annealing Induced Crystal Control for Efficient Wide-Bandgap Perovskite Solar Cells |
초록 |
Despite the remarkable attraction of wide-bandgap perovskite solar cells (WBG PSCs), such as high open-circuit voltage (Voc) >1.2 V and complementary absorption for conventional silicon (Si) based solar cells, their low performance has been one of the most serious bottlenecks toward the real application of the WBG PSCs such as Si/perovskite tandem solar cells. Here, we have reported an annealing induced crystal control process of WBG perovskite crystal and revealed that the process can increase crystal size of the WBG perovskites. By optimizing annealing process of the perovskite, we improved the power conversion efficiency of the WBG PSCs to 18% with a high Voc (over 1.24 V). |
