【Abstract】 External quantum efficiency( EQE) of( FAPb I3)1-x( MAPbBr3)xperovskite solar cell was simulated based on the actual optical constants obtained by fitting the measured transmittance and reflectance spectra of each layer in the device. The simulated results show an error below 1% compared with the measured EQE curve. The optical losses of the perovskite solar cell were analyzed and the thickness of transparent conductive electrode,electron transport layer,and perovskite materials were optimized. The effect of transparent conductive electrode,electron transport layer and perovskite absorber layer on device performance were studied. This simulation can effectively reduce the amount of experiments and provide some guidance for quickly achieving a high-performance device.更多还原
