چکیده
Perovskite Solar Cells In article number 2302418, Hyungjun Kim, Ki-Ha Hong, Sang Hyuk Im, Chang Eun Song, and co-workers demonstrate a defect-passivation strategy using L-asparagine, which can effectively suppress tin oxidation. L-asparagine as zwitterion revolutionizes film morphology energy-level matching, boosting power conversion efficiency to remarkable 13.31%. Surpassing limitations are tied halide perovskite instability. This work offers transformative insights practical strategies for advancing tin-based electronic devices.

15 صفحه اولHigh Performance Perovskite Solar Cells
Perovskite solar cells fabricated from organometal halide light harvesters have captured significant attention due to their tremendously low device costs as well as unprecedented rapid progress on power conversion efficiency (PCE). A certified PCE of 20.1% was achieved in late 2014 following the first study of long-term stable all-solid-state perovskite solar cell with a PCE of 9.7% in 2012, sh...
