Summary:CH3NH3PbI3 perovskite photovoltaic devices inserted with a polysilane layer were fabricated and characterized. A Decaphenylcyclopentasilane (DPPS) in chlorobenzene solution was spin-coated between the perovskite layer and the hole transport layer of spiro-OMeTAD, and the resulting device was annealed at 190 °C. The DPPS-treated devices had higher conversion efficiencies than the standard ones, and they were stable in ambient air. Microstructural observations suggested that DPPS would work effectively as a bulk-hetero structure with perovskite layers.
