On the Current Conduction and Interface Passivation of Graphene–Insulator–Silicon Solar Cells
Published on 2025-03-08 by Hei Wong, Jieqiong Zhang, Jun Liu, Muhammad Abid Anwar @MDPI
Abstract: Interface-passivated graphene/silicon Schottky junction solar cells have demonstrated promising features with improved stability and power conversion efficiency (PCE). However, there are some misunderstandings in the literature regarding some of the working mechanisms and the impacts of the silicon/insulator interface. Specifically, attributing performance improvement to oxygen vacancies and characterizing performance using Schottky barrier height and ideality factor might not be the most accura[...]
Our summary: Interface-passivated graphene/silicon Schottky junction solar cells show improved stability and power conversion efficiency, with a focus on Al2O3 interface ALD growth on silicon and its impact on MIS solar cells. Current conduction in MIS solar cells with a 2 to 3 nm insulating layer is better described by direct tunneling, Poole-Frenkel emission, and Fowler-Nordheim tunneling. Key factors for process optimization include dielectric film thickness, band offset with Si, and interface roughness.
