High-Efficiency Perovskite/Silicon Tandem Solar Cells Based on Wide-Bandgap Perovskite Solar Cells with Unprecedented Fill Factor.

ABSTRACT: Recent progress in inverted perovskite solar cells (iPSCs) highlights the critical role of interface engineering between the charge transport layer and perovskite. Self-assembled monolayers (SAM) on transparent conductive oxide electrodes serve effectively as hole transport layers, though challenges such as energy mismatches and surface inhomogeneities remain. Here, a blended self-assembled monolayer of (2-(9H-carbazol-9-yl)ethyl)phosphonic acid (2PACz) and (4-(3,6-Dimethyl-9H-carbazol-9-yl)butyl)phosphonic acid (Me-4PACz) is developed, offering improved surface potential uniformity and interfacial energy alignment compared to individual SAMs. Interactions between the SAMs and ionic species are investigated with simulation analysis conducted, revealing the elimination of interfacial energy
