MDACl₂-Modified SnO₂ Film for Efficient Planar Perovskite Solar Cells.

ABSTRACT: The electron transport layer (ETL) with excellent charge extraction and transport ability is one of the key components of high-performance perovskite solar cells (PSCs). SnO₂ has been considered as a more promising ETL for the future commercialization of PSCs due to its excellent photoelectric properties and easy processing. Herein, we propose a facile and effective ETL modification strategy based on the incorporation of methylenediammonium dichloride (MDACl₂) into the SnO₂ precursor colloidal solution. The effects of MDACl₂ incorporation on charge transport, defect passivation, perovskite crystallization, and PSC performance are systematically investigated. First, the surface defects of the SnO₂ film are effectively passivated, result
