Enhancement of All-Inorganic Perovskite Solar Cells by Lead–Cerium Bimetal Strategy
Source abstract
Abstract
Owing to the instability of organic materials, an inorganic perovskite solar cell (PSC) attracts much attention in recent years. However, the instability of phase and overmuch traps lead to the inferior performance of inorganic perovskite solar cell, a high performance inorganic PSC is desirable. The element of cerium possesses a suitable chemical and physcial properties to substitute lead. We utilize cerium to partially substitute lead, a lead–cerium (Pb–Ce) bimetal based inorganic PSC is successfully achieved to modify the stability of PSC, the CsPb0.85Ce0.1I3 based PSC exhibits a champion PCE (power conversion efficiency) of 17.57%, and the tolerance of thermal, illumination, and environmental are enhanced among 10–20%. The enhanced PCE is ascribed to the structure of lead–cerium (Pb–Ce) bimetal perovskite absorbing layers and high quality of perovskite film.
