Abstract

Abstract : In article number 1903085, Jaejin Lee, Hui Joon Park, and co‐workers demonstrate perovskite/GaAs 2‐ and 4‐terminal tandem cells. High performance, stable, wide‐bandgap perovskite photovoltaics (PVs) (1.8–1.9 eV) are developed through a solvent‐controlled process. The tandem architecture is also feasible for a thin‐film flexible PV, which is essential to reduce its cost for commercialization with superior bendability. This approach is expected to improve the usability of GaAs PVs with enhanced efficiency and lower cost for applications where light‐weight and flexibility are critical.
