Embodiment Construction

[0028] like figure 1 , 2 As shown, two kinds of metal wires with different electron number densities are arranged in the high temperature layer 1, heat insulation layer 2 and low temperature layer 3 below the convex lens 4, i.e. the first metal wire 6 and the second metal wire 7, the first metal wire 6 One end of a is placed in the low-temperature layer 3, and the other end is placed in the high-temperature layer 1. One end c of the second metal wire 7 is also placed in the low-temperature layer 3 , and the other end is connected to the first metal wire 6 at b and placed in the high-temperature layer 1 . In this way, the first metal wire 6 and the second metal wire 7 constitute the first group of thermocouples on the left side. In the same way, the first metal wire 6 and the second metal wire 7 constitute the second group of thermocouples on the right side. Two thermocouples are connected in series to form a thermopile; the two ends a and e of the thermopile will obtain tw...

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...
