Radiator of solar cell with high concentration magnification and method for manufacturing the same

Abstract

The invention discloses a radiator of a solar cell with a high concentration magnification. The radiator is composed of a copper thin layer, a silver-copper-titanium alloy layer, a diamond film, a silver-copper-titanium alloy layer, and a copper pedestal. he copper thin layer is formed under a concentration solar cell and one silver-copper-titanium alloy layer is formed under the copper thin layer, wherein an insulation channel is formed by the copper thin layer and the silver-copper-titanium alloy layer; the diamond film is formed under the silver-copper-titanium alloy layer; and the other silver-copper-titanium alloy layer is formed under the diamond film; the copper pedestal is formed under the other silver-copper-titanium alloy layer; and a cooling water channel is formed under the copper pedestal. In addition, a method for manufacturing the radiator is disclosed. The radiator provided in the invention can be applied to a concentration solar cell with a concentration magnification of over 1,600 times, wherein the integral thermal conductivity reaches over 400W / (m .k); the radiating effect of the radiator provided in the invention is better than that of the AL2O3ceramic radiator whose thermal conductivity is 280W / (m .k). Therefore, the radiator provided in the invention has a high-efficient radiating effect, so that the concentration solar cell can work stably under the condition of high concentration magnification, and the decline of the photoelectric conversion efficiency can be reduced.

Description

technical field [0001] The invention relates to a heat dissipation device for a concentrating solar cell, in particular to the application of special materials and structures as a heat dissipation device for a concentrating solar cell and a manufacturing method. Background technique [0002] The traditional fuel energy is gradually scarce, and the harm to the environment is becoming more and more prominent. As solar energy is an inexhaustible renewable energy treasure house on the earth, it has become the consensus of governments of all countries to vigorously develop the photovoltaic industry. Experts predict that solar power generation will account for 50% of the world's total power generation by 2030. [0003] When the whole world is investing in the photovoltaic industry, concentrating solar cells are the most advantageous among all forms of solar cells. At present, concentrator cells have appeared in the international market, especially represented by European and Amer...

Problems solved by technology

With the increase of the concentrating multiple, the temperature of the concentrating solar cell rises sharply. If the heat is not quickly dissipated, it will not only lead to a decrease in power generation efficiency, but also burn out the battery chip.
