Abstract

Perovskite solar cells (PSCs) have experienced an unprecedented advancement in the last decade owing to their astonishingly attractive properties, especially high-power conversion efficiency (PCE). In this study, the influence of reduced graphene oxide (rGO) on the photovoltaic performance of perovskite solar cells prepared via solution processes-based spin coating method was investigated. X-ray Diffraction (XRD), Fourier Transform Infrared spectrometer (FTIR), UV-visible spectrophotometry, Scanning Electron Microscopy (SEM) were used to study the properties of the prepared films. ITO/MAPbBr3/Gr and ITO/rGO/MAPbBr3/Gr planar PSCs were fabricated via spin coating method. ITO/rGO/MAPbBr3/Gr film achieved a power conversion efficiency (PCE) of 4.1 short circuit current (Jsc) of 7.5 mAcm−2 and fill factor (FF) of 61.2% compared to a PCE of 3.6%, Jsc of 6.6 mAcm−2 and FF of 58.0% achieved compared to PCE of 3.6%, %, Jsc of 6.6 mAcm−2 and FF of 58.0% achieved by ITO/MAPbBr3/Gr film. The PSC demonstrated the percentage enhancement value of 16.80% when modified with rGO. This study shows that rGO generated functional groups that act as conducting bridge in reducing the contact resistance between interface of the device.
