摘要:
A photovoltaic device and method include a doped transparent electrode, and a light-absorbing semiconductor structure including a first semiconductor layer. An ultra-thin layer of a non-transparent metal is formed between the transparent electrode and the first semiconductor layer to form a reduced barrier contact wherein the ultra-thin layer is light transmissive. When the ultrathin metal forms discrete individual dots, it permits a plasmonic light trapping effect to increase the current at solar cells.
