摘要:
A method is disclosed for operating a photovoltaic thermal hybrid system having a hybrid solar receiver with a photovoltaic module, operatively coupled to the system to deliver an electrical output power for a power user, a thermal collector distinct from the photovoltaic module, wherein the photovoltaic module and/or the thermal collector are movably mounted in the system, a collector thermal storage thermally connected to the thermal collector to store heat collected at the thermal collector, and a positioning mechanism adapted to move the photovoltaic module and/or the thermal collector. The method includes instructing the positioning mechanism to move the photovoltaic module and/or the thermal collector to change a ratio of an intensity of radiation received at the photovoltaic module to an intensity of radiation received at the thermal collector.

摘要:
A Schottky-barrier-reducing layer is provided between a p-doped semiconductor layer and a transparent conductive material layer of a photovoltaic device. The Schottky-barrier-reducing layer can be a conductive material layer having a work function that is greater than the work function of the transparent conductive material layer. The conductive material layer can be a carbon-material layer such as a carbon nanotube layer or a graphene layer. Alternately, the conductive material layer can be another transparent conductive material layer having a greater work function than the transparent conductive material layer. The reduction of the Schottky barrier reduces the contact resistance across the transparent material layer and the p-doped semiconductor layer, thereby reducing the series resistance and increasing the efficiency of the photovoltaic device.
