In this study, a novel hybridized perovskite-Cu2ZnSnS4 solar cell has been demonstrated. The CH3NH3PbI3 layer was synthesized using a facile one-step solution process under ambient conditions. The precursor solution consists of an equimolar methylammonium ion [MA+] and [PbI3 ] anion in heptane solvent. The vapor-assisted crystal growth at the grain boundaries occur due to the methylamine (CH3NH2, MA). Moreover, 1 wt% Cu2ZnSnS4 (CZTS) nanoparticles (NPs) was added to the solution to enhance not only the absorption from visible to infrared regions and but also the transfer of the photogenerated charge carriers, leading to reduced charge recombination. The device structure was glass/ITO/1 wt% CZTS NPs hybrid poly (3,4-ethylenedioxythiophene) poly (styrene-sulfonate) (PEDOT:PSS)/CH3NH3PbI3 (MAPbI3)/C60/BCP/Al. The obtained MAPbI3 perovskite-based solar cell shows a short-circuit current density of 19.00 mA/cm2, an open-circuit voltage of 0.84 V, a fill factor of 0.47, and a power conversion efficiency (PCE) of 7.55%.
