A highly efficient mesoscopic solar cell based on CH₃NH₃PbI(3-x)Cl(x) fabricated via sequential solution deposition.
A mixed halide perovskite of CH3NH3PbI(3-x)Cl(x) is synthesized via two-step sequential solution deposition by using a mixture of PbCl2 and PbI2 as the precursor to overcome the low solubility of pure PbCl2 with easy morphology control. 11.7% power conversion efficiency is achieved for the mesoscopic cell, much higher than the cell constructed via a spin-coating process.
