Gas Quenched Alternating Cations in the Interlayer Space Quasi-2D (GA)(MA)5Pb5I16 Perovskite for Radiation Tolerant Single Junction and Stable Monolithic Quasi-2D Perovskite-Silicon Tandem Solar Cells

Abstract

Here, we report gas-quenched quasi-2D (GA)(MA)5Pb5I16 perovskites for single junction solar cells and monolithic-silicon tandem solar cells. This is the first time quasi-2D (GA)(MA)5Pb5I16 perovskite cells have been tested with proton beams, showing excellent tolerance. A representative tandem cell also passed the IEC 61215 Thermal Cycling Test (−40 °C ↔ 85 °C) twice, retaining 95.0% of its initial PCE after 400 cycles. Show more
