Design and optimization of the plasmonic graphene/InP thin-film solar-cell structure

摘要

In this paper, a graphene/InP thin-film Schottky-junction solar cell with a periodic array of plasmonic back-reflector is proposed. In this structure, a single-layer graphene sheet is deposited on the surface of the InP to form a Schottky junction. Then, the layer stack of the proposed solar-cell is optimized to have a maximum optical absorption of AW = 0.985 (98.5%) and short-circuit current density of J(sc) = 33.01 mA cm(-2).
