High‐performance hole‐selective V2OX / SiOX / NiOX contact for crystalline silicon solar cells

Abstract High work function vanadium oxide (V2OX, X < 5) is expected to induce strong upward band bending at crystalline silicon (c‐Si) surface thus selectively collect photogenerated hole‐carriers. However, the performance of c‐Si solar cells employing V2OX‐based hole‐selective contacts is still un... View More
