Quasi-blackbody absorbent high-efficient concentration solar cell assembly

Abstract

The invention relates to a photoelectrical conversion module of a concentrating photovoltaic system, which belongs to the technical field of solar utilization technique. The photoelectrical conversion module mainly comprises a strip-like lens array (19), a silicon battery (10), a flexible electrode (18), a conductive heat dissipation metal component (13), etc. The photovoltaic battery cell (10) has a strip shape, and the flexible contact electrode (18) with larger contact surface and the conductive heat dissipation metal component (13) with electrical conduction and heat dissipation functions are packaged on both sides of the upper surface of the photovoltaic battery cell (10) in a contact manner. The strip-like condensing lens array (19) is used for condensing parallel beams vertical to the upper surface, and the beams irradiate the region between two flexible electrodes on the surface of the photovoltaic battery cell after being condensed and diverged for one time. Continuously reflected by an upper space with a reflection layer, the most of the light beams are absorbed by the photovoltaic battery cell. The metal component (13) can transfer the heat of the photovoltaic battery cell (10). The solar battery assembly having the structure has smaller size and larger condensation multiple.

Description

technical field

[0001] The invention relates to a photoelectric conversion module of a concentrated photovoltaic system, belonging to the technical field of solar energy utilization. Background technique

[0002] The existing concentrating solar photovoltaic cell power generation basically uses a convex lens or a Fresnel lens and a catadioptric mirror to irradiate the solar photovoltaic cell with sunlight to generate electricity. The main reason for this is because of the higher production costs of photovoltaic cells. How to use fewer photovoltaic cells to generate more electricity is the goal pursued by many researchers. According to the performance characteristics of conventional solar photovoltaic cells, the output power of photovoltaic cells is basically proportional to the light intensity under the sunlight irradiation of low-magnification lenses below 10 times. However, since the temperature generated by concentrated light has a great influence on the performance of ...
