Efficient and Stable Monolithic Perovskite/Silicon Tandem Solar Cells Enabled by Contact‐Resistance‐Tunable Indium Tin Oxide Interlayer

The imperfect charge behavior at the interfaces of perovskite/electron-transport layer (ETL)/transparent conducting oxide (TCO) limits the further performance improvement of perovskite/silicon tandem solar cells. Herein, an indium tin oxide interlayer is deposited between ETL and TCO to address this issue. Specifically, the interlayer is prepared using an all-physical and H
