【 摘 要 】

Herein, organic-free all-solid-state based perovskite solar cells (PSCs) are successfully fabricated by one-step method. The absorption position of the non-perovskite cesium lead iodide (δ-CsPbI 3 ) was significantly shifted towards longer wavelength side by substituting indium (In) ion with different stoichiometric ratio. The authors demonstrated a facile route to achieve high efficiency by the fabrication of room temperature stable mixed-phase CsPbI 3 perovskite. Photovoltaic efficiency of doped perovskite is four times increased compared to pure yellow phase CsPbI 3 . To the best of the authors’ knowledge, this is the first demonstration of In-doped-CsPbI 3 based PSCs, which was fabricated under completely open-air atmosphere.
