A concentrating and stacked solar energy utilization device

Abstract

This invention provides a solar concentrating and cascading solar energy utilization device, comprising, from top to bottom, a semi-transparent photovoltaic cell module, a point-type convex lens concentrator array, a micro-collector unit, a hot fluid pipeline, and a heat storage / chemical reaction module. The semi-transparent photovoltaic cell module is mounted on top of the system; the point-type convex lens concentrator array is positioned below the semi-transparent photovoltaic cell module, and each collector in the micro-collector unit is located at the focal point of the corresponding concentrator in the point-type convex lens concentrator array; the hot fluid pipeline is used to transport the heat collected by the micro-collector unit to the heat storage / chemical reaction module. This invention achieves photoelectric conversion through the semi-transparent photovoltaic cell module, enhances photothermal density through secondary focusing by the point-type convex lens concentrator array, efficiently collects heat through the micro-collector unit, and coordinates the hot fluid pipeline and the heat storage / chemical reaction module to achieve spectral division and cascaded utilization of solar energy, providing an efficient solution for comprehensive solar energy utilization.
