摘要：
Perovskite solar cells, in which decaphenylcyclopentasilane (DPPS) layers were formed on the surface of the CH3NH3PbI3 perovskite layer, were fabricated and characterized. The photovoltaic properties were improved by controlling the annealing temperature of the perovskite layer. For perovskite layers annealed at high temperatures of similar to 200 degrees C, the perovskite crystals were densely formed and the surface coverage of the perovskite layer was improved. The DPPS-laminated devices suppressed the formation of PbI2 crystals and the stability was improved by the DPPS layer.
