【 摘 要 】

Polysilane-inserted CH₃NH₃PbI₃ perovskite photovoltaic devices combined with potassium and formamidinium iodides were fabricated and characterized. Decaphenylcyclopentasilane layers were inserted at the perovskite/hole transport interface and annealed across a temperature range of 180–220 °C. These polysilane-coated cells prevented PbI₂ formation, and the conversion efficiencies were improved over extended periods of time.
