Mixed lead-tin （Pb-Sn） perovskites present a promising strategy to extend the light-harvesting range of perovskite-based solar cells （PSCs）. The use of electron- transporting layer or hole-transporting layer （HTL） is critical to achieve high device efficiency. This strategy, however, requires tediou...
