Abstract

To enhance the performance of planar type CH3NH3PbI3 (MAPbI3) perovskite solar cells, we introduced MAPbBr3 because MAPbBr3 exhibits longer charge carrier's diffusion length than the MAPbI3. Although the absorption of MAPbI3-xBrx (x = 0.045) perovskite material is blue-shifted to ∼ 4 nm than that of MAPbI3-xBrx (x = 0), the MAPbI3-xBrx (x = 0.045) solar cell showed ∼ 17.7 % enhanced performance (1.14 Voc, 22.1 mA/cm2 Jsc, 81.3 % FF and 20.6 % efficiency) than the MAPbI3-xBrx (x = 0) device (1.10 Voc, 20.1 mA/cm2 Jsc, 79.2 % FF and 17.5 % efficiency).
