Abstract

Different additive materials have been extensively investigated in hybrid perovskite solar cells (PSC) to enhance the crystal growth, minimize defects and to improve the device stability. However, most of the additive engineering attempts are basically dedicated to the improvement of open circuit voltage (Voc) in PSC. There are very few investigations where PSC’s short circuit current density (Jsc) is significantly improved along with the Voc. In this work, a novel organic additive material called Phenylhydrazinium iodide (PHI) has been employed to enhance the Jsc hence the overall power conversion efficiency (PCE) of CH3NH3PbI3 PSC. Surprisingly, after PHI treatment Jsc jumps from around 20 to 23 mA/cm2 which corresponds to ~15% increase of short circuit current density resulting overall 21% improvement in PCE. PHI treatment in wide-bandgap perovskite will help to mitigate the problem of shorter Jsc in compared to low-bandgap perovskite materials in multi-junctional tandem solar cell.
