Abstract Polysilane-inserted C[H.sub.3]N[H.sub.3]Pb[I.sub.3] 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 [degrees]C. These polysilane-coated cells prevented Pb[I.sub.2] formation, and the conversion efficiencies were improved over extended periods of time.
