Problems solved by technology
However, due to the use of two-stage or multi-level concentrating to correct the error of the concentrating point and the use of traditional aluminum radiators to increase the product cost, the product cost is too high, which greatly limits the scope of application
In particular, the domestic introduction of EMCORE's products still has disadvantages such as large floor space

Disclosed in the invention is a gallium-arsenide concentrating photovoltaic power generation system comprising a concentrating photovoltaic assembly, a support system, a solar energy tracking system, and a deceleration driving mechanism. The concentrating photovoltaic assembly is formed by series connection of Fresnel lenses and multi-junction-surface gallium-arsenide solar receivers, wherein the number of the Fresnel lenses and the number of the multi-junction-surface gallium-arsenide solar receivers are identical; and the concentrating photovoltaic assembly is connected with the deceleration driving mechanism by the support system. The solar energy tracking system and the deceleration driving mechanism are electrically connected and the solar energy tracking system controls the deceleration driving mechanism to move. With the system, the solar tracking precision is improved; the two-stage or multi-stage concentrating crystal pyramid trustum is removed; and the luminous flux is improved. With the heat radiation technology different from the Euramerican heat radiation technology, the heat radiation efficiency is improved; safety of the gallium-arsenide chip is guaranteed and the photovoltaic conversion efficiency is improved; the product cost is reduced; the project return rate is substantially improved to 29.32%; and the rational-price networking of the gallium-arsenide concentrating photovoltaic power generation can be guaranteed.
Description
technical field [0001] The invention relates to the field of solar photovoltaic power generation systems, in particular to a gallium arsenide concentrating photovoltaic power generation system. Background technique [0002] With the strengthening of environmental awareness around the world, non-polluting new energy technologies are highly respected by all countries. Solar energy is an inexhaustible clean energy for human beings. Its utilization not only solves the problem of fossil energy that is becoming exhausted, but also effectively reduces environmental pollution. Therefore, it is an effective way to develop and utilize new energy and protect the environment. At present, monocrystalline silicon, polycrystalline silicon solar cells and amorphous silicon thin-film solar cells are the most widely used solar cells in China. However, they have problems such as high energy consumption, long energy repayment period, low power generation, and large footprint. . [0003] As e...
