Abstract
- Formamidinium lead iodide (FAPbI<subscript>3</subscript>) is a promising candidate as the solar cell absorption layer with a suitable band gap of 1.45 eV and excellent optoelectronic properties. In this work, we report a new vacuum flash evaporation method to deposit phase-pure black α-FAPbI<subscript>3</subscript> films in situ on low-temperature substrates without post-annealing, and the area of deposited films can be up to 36 cm<superscript>2</superscript> (6 cm × 6 cm). Besides, the unique relationship between substrate temperature and phases in films is demonstrated for the further development of the method. With the α-FAPbI<subscript>3</subscript> films as the active layer, perovskite solar cells with power conversion efficiency of 12.55% are fabricated. [ABSTRACT FROM AUTHOR]
