Abstract
Passivating the grain boundaries is completely very crucial in the enhancement of the performance of halide perovskite solar cells (PSCs). Here, a novel organolead halide perovskite (CH3NH3PbI3) was synthesized using solution processes-based method to sensitize 1D titanium dioxide (TiO2) and reduced graphene oxide (RGO) nanoparticles for all-solid-state halide perovskite solar cells. TiO2 and RGO were synthesized via sol-gel and Hummers’ methods, respectively, and incorporated at the electron transport layer (ETL) in planar PSCs. Additionally, MnO2was prepared by chemical method, and used to enhance graphite counter electrode. ITO/RGO/TiO2/CH3NH3PbI3/Gr and ITO/RGO/TiO2/CH3NH3PbI3/Gr-MnO2 planar PSCs were fabricated via spin coating method. ITO/RGO/TiO2/CH3NH3PbI3/Gr-MnO2 film achieved a power conversion efficiency (PCE) of 10.79%, short circuit current (Jsc) of 19.0 mAcm-2 and fill factor (FF) of 51.53% compared to PCE of 8.64%, Jsc of 16.25 mAcm-2 and FF of 47.48% achieved for ITO/RGO/TiO2/CH3NH3PbI3/Gr film. The enhancement value of 22.85% was achieved from J-V curves after exposing the ITO/RGO/TiO2/CH3NH3PbI3/Gr and ITO/RGO/TiO2/CH3NH3PbI3/Gr-MnO2 films to Keithley 2400 sourcemeter (Keithley Instrument Inc.) under AM 1.5G (100 mWcm-2) (Newport) solar illumination in order to test their photovoltaic performance. This study shows that MnO2 nanoparticle has a proven capability to improve the photovoltaic performance of PSCs.
