Abstract

In the solar energy application system, in order to improve the efficiency of solar cells and the utilization of light energy, the paper studies the solar tracking system with concentrating device and using germanium solar cells. This paper compares the differences between germanium cells and silicon cells in terms of photoelectric conversion efficiency and output characteristics, and demonstrates the superiority of germanium solar cells. Several common types of concen-trating devices such as Fresnel lenses, trough concentrators, tower concentrators and disc con-centrators were listed, and the disc concentrator was finally selected considering the concen-trating performance and cost. The paper also analyzes the solar operation law and the charac-teristics of various tracking devices, and on the basis of comprehensive analysis of the ad-vantages and disadvantages of various tracking devices, a hybrid tracking scheme is proposed. After completing the design of the system structure, the efficiency and cost of the traditional fixed solar system and the concentrated germanium solar power generation sunny system are compared and analyzed by SIMULINK modeling, and the results show that the solar energy utilization rate and power generation efficiency of the system designed in this paper are greatly improved, which verifies the effectiveness and economy of the system. The concentrating germanium solar power generation system not only adopts germanium cells with better photo-electric characteristics, but also adds a concentrating device and a sun tracking device, which greatly improves the efficiency of solar power generation. And the volume of the device is not large, which can realize the promotion of small home solar energy systems.
