The addition of Cu@RGO as a hole transport layer in PSCs improved the photoconversion efficiency, outperforming Ag@RGO and pure RGO, and exhibited good shelf stability.
In this work, we explore the addition of reduced graphene oxide (RGO) decorated with copper (Cu@RGO) as hole transport layer (HTL) into carbon/CH3NH3PbI3/TiO2/FTO perovskite solar cell (PSC). Numerous instrumentations characterized the fabricated composites. The deposited Cu on RGO showed spherical metallic particles with diameters of 22-30 nm. Current density-voltage curves and Incident photon-to-electron conversion explore the impact of Cu@RGO on the photoconversion efficiency (PCE). The fashioned Cu@RGO nanocomposite showed improved PCE at 13.55% compared to 11.3 and 5.5% for the PSCs with Ag@RGO and pure RGO as HTL, respectively. These impacts are due to the significant hole extraction that proved by the photoluminescence quenching. Moreover, the produced devices with Cu@RGO displayed shelf stability at 88.8% of its initial PCE after two months. This work marks an important milestone towards the development of solar cells with reliable and high-performance perovskites. (C) 2021 The Author(s). Published by Elsevier B.V.
