Abstract

A power conversion efficiency of 10.4% is demonstrated in planar CH₃NH₃PbBr₃ hybrid solar cells without hysteresis of the J-V curve, by way of controlled crystallization in the spin-coating process. The high efficiency is attributed to the formation of a dense CH₃NH₃PbBr₃ thin film by the introduction of HBr solution because the HBr increases the solubility of the CH₃NH₃PbBr₃ and forms a thinner CH₃NH₃PbBr₃ layer with full surface coverage. (Graph Presented).
