The Investigation of the Influence of a Cu₂O Buffer Layer on Hole Transport Layers in MAPbI₃-Based Perovskite Solar Cells.

ABSTRACT: The passivation engineering of the hole transport layer in perovskite solar cells (PSCs) has significantly decreased carrier accumulation and open circuit voltage (V_oc) loss, as well as energy band mismatching, thus achieving the goal of high-power conversion efficiency. However, most devices incorporating organic/inorganic buffer layers suffer from poor stability and low efficiency. In this article, we have proposed an inorganic buffer layer of Cu₂O, which has achieved high efficiency on lower work function metals and various frequently used hole transport layers (HTLs). Once the Cu₂O buffer layer was applied to modify the Cu/PTAA interface, the device exhibited a high V_oc of 1.20 V, a high FF of 75.92%, and an enhanced P
