Perovskite-based inverted structure of solar cells with TiO2, graphene oxide (GO), and TiO2-GO
photo-anodes were analyzed by SCAPS profile. The photovoltaic performance showed thatGO
produces the maximum power conversion efficiency of 10.34% under illumination. Quantum
efficiency, carrier generation, recombination and concentrations through layers of devices were
investigated. Then, the impact ofGOthickness on photovoltaic characteristics was investigated to
optimize theGOthickness. By optimizing the thickness of theGOlayer, the efficiency of the device
improved from 10.34% to 10.91% in the thickness of 40 nm. These simulation results could provide
guidelines to fabricate higher efficiency solar cells.
