Pd(II)/Pd(IV) redox shuttle to suppress vacancy defects at grain boundaries for efficient kesterite solar cells - Nature Communications

May 21, 2024 | nature.com | Jiangjian Shi |Fanqi Meng |Yanhong Luo |Dongmei Li |Shiyou Chen

AbstractCharge loss at grain boundaries of kesterite Cu2ZnSn(S, Se)4 polycrystalline absorbers is an important cause limiting the performance of this emerging thin-film solar cell. Herein, we report a Pd element assisted reaction strategy to suppress atomic vacancy defects in GB regions.
