Optical-thermal-electric integrated power-generation module

Abstract

The invention relates to an optical-thermal-electric integrated power-generation module, which comprises a module body, wherein the module body comprises three layers, which are a high-temperature layer, a thermal insulation layer and a low-temperature layer and arranged thereon from top to bottom. The high-temperature layer is an optical energy accumulation layer, and a plurality of convex lenses are distributed on the upper surface of the high-temperature layer. Two kinds of metal wires with different electron number densities are distributed inside the high-temperature layer, the thermal insulation layer and the low-temperature layer below the convex lenses and are connected with each other to form a thermal electric couple; the joints are placed in the high-temperature layer and the low-temperature layer respectively; and a plurality of thermal electric couples are connected in series to form a thermopile. A single convex lens and the thermopile corresponding to the convex lens form a generating unit; and a plurality of generating units are connected in series or in parallel to form a generating module. The optical-thermal-electric integrated power-generation module improves the utilization rate of optical energy, has higher power generation production than that of a photovoltaic power-generation of the same area, as well as low manufacturing cost and no pollution, and is easy to popularize.

Description

Technical field [0001] The present invention involves a solar power generation device, which specifically involves an optical and heat -power integrated power generation module based on solar collecting temperature difference power generation technology. [0002] Background technique [0003] Solar energy is clean and cheap energy, making full use of it, which is of great significance.The existing solar collecting boards are flat -flat type and some are cylindrical collection.Because the former's reflection of light and the latter gap between the latter leaks a lot of light energy, a considerable part of the light energy can not be used. [0004] The photovoltaic battery that converts light energy to electrical energy has low conversion efficiency (about 11%-13%of commercial products); the production of silicon materials for the production of photovoltaic batteries is severely scarce, the production cost is high and the pollution is serious.More than times, these factors have ser...

Problems solved by technology

[0004] Photovoltaic cells that convert light energy into electrical energy have low conversion efficiency (commercialized products are about 11%-13%); silicon materials for the production of photovoltaic cells are in serious shortage, the production cost is high and pollution is serious, and the on-grid electricity price is 10% of coal electricity These factors have seriously affected and restricted the large-scale promotion and use of photovoltaic cells.
