Light-splitting reflection high-concentration photovoltaic photothermal integrated cavity receiver

A light-splitting reflection high-concentration photovoltaic photothermal integrated cavity receiver, comprising a photothermal assembly and a photovoltaic assembly,

• wherein the photothermal assembly comprises a high-temperature heat storage system, a low-temperature heat storage system, a plurality of heat exchange tube bundles defining a reflective cavity, and an ultraviolet and visible light reflective film arranged on an inner surface of the reflective cavity, the ultraviolet and visible light reflective film having less reflectivity than transmittance for light with a wavelength greater than 900 nm, the plurality of heat exchange tube bundles are communicated to form a heat collection circuit, and the heat collection circuit has an input end connected with the low-temperature heat storage system, and an output end connected with the high-temperature heat storage system,
• wherein the photovoltaic assembly is arranged at a focus of the reflective cavity, and comprises a near-infrared reflective film, a high concentration photovoltaic integrated receiver and a concentration photovoltaic cooler stacked sequentially along an incident direction of light;
• wherein the high concentration photovoltaic integrated receiver is an integral receiver composed of multijunction gallium arsenide high concentration photovoltaic cells.
