A power conversion efficiency of 10.4% is demonstrated in planar CH3 NH3 PbBr3 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 CH3 NH3 PbBr3 thin film by the introduction of HBr solution because the HBr increases the solubility of the CH3 NH3 PbBr3 and forms a thinner CH3 NH3 PbBr3 layer with full surface coverage.
通过在旋涂过程中控制结晶，在无迟滞的 J-V 曲线的情况下，平面 CH3 NH3 PbBr3 混合太阳能电池的功率转换效率达到了 10.4%。高效率归因于通过引入 HBr 溶液形成致密的 CH3 NH3 PbBr3 薄膜，因为 HBr 增加了 CH3 NH3 PbBr3 的溶解度，并形成具有完全表面覆盖的更薄的 CH3 NH3 PbBr3 层。
