Recently, Organometallic trihalide perovskites have been commonly studied owing to their outstanding optoelectronic characteristics. The current study uses reduced graphene (rGO) into perovskite solution as harvester layer for efficient mesoscopic perovskite solar cells (PSCs). We systematically investigated the impact of rGO additive on the optoelectronic performance properties of PSCs. The perovskite film with the rGO exhibited a dense and pinhole-free film with good crystalline nature. While, the devices without the rGO additive suffered from severe recombination process, which was investigated with photoluminescence (PL) spectroscopy. Consequently, the device with the rGO exhibited a power conversion efficiency (PCE) of 11.55%, together with an open voltage (Voc) of 0.934 V, a short current density (Jsc) of 17.67 mA/cm(2) and a fill-factor (FF) of 70%.
