Quinoxaline‐Based Materials That Exhibit a Significant Passivation Effect and Lead to the Enhancement in the Power Conversion Efficiency of Perovskite Solar Cells

Perovskite Solar Cells In article number 2300692, Chow, Chang, and co-workers employed Qu-CN as the hole transport material and Qu-COOH as the passivator on the surface of perovskite. Through this optimization, the perovskite has transitioned into the α/δ phase MAPbI3. This advancement has culminated in an impressive power conversion efficiency of 20.64% and excellent device stability in n-i-p PSCs.
