    摘要： A photovoltaic cell includes an absorbing layer configured to generate electron-hole pairs from incident photons of incoming light; and a first grating layer arranged at a first surface of the absorbing layer which is opposite to a second surface of the absorbing layer from which light is incident, wherein the first grating layer includes at least one grating extending along the first surface, wherein the at least one grating has grating structures which are dimensioned to provide a reflectivity for light incident through the absorbing layer back into the absorbing layer.

    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.
