Problems solved by technology

[0004] However, the above-mentioned structure adopts a funnel-shaped secondary optical homogenization mirror structure. Due to the deviation of the angle of the solar tracking system, it is easy to cause light leakage and too small spot of concentrated solar light, which will cause the chip temperature of the solar high-power concentrated photovoltaic power generation module. Disadvantages such as too high, performance drop, too high chip temperature and insufficient chip effective area utilization

Embodiment Construction

[0024] Such as figure 1 As shown, the secondary optical homogenizing mirror realized by the present invention is usually applied in a solar high-power concentrating photovoltaic power generation module. figure 2 As shown, the uniform light mirror 1 is a square conical structure with a large top and a small bottom. The upper conical surface 3 is large, and the lower conical surface 4 is small. The solar chip 5 is arranged at the bottom of the lower conical surface 4, and the solar chip 6 is again fixed on the substrate 6.

[0025] The cross-section of the uniform light mirror 1 is a square, which is convenient for light refraction; the diameter of the bottom of the hemispherical surface 2 covered by the upper conical surface 3 is consistent with the diameter length and width of the upper conical surface 3, so that the hemispherical body 2 can It is completely covered and fixed on the upper conical surface 3, and the size of the upper conical surface 3 is generally determined ...

Abstract

The invention relates to a secondary optical dodging mirror structure of a light concentrating photovoltaic module, which adopts a square taper with the upper part larger than the lower part. The upper surface of the square tapered dodging mirror is provided with a protruding spherical surface. Sunlight through the secondary optical dodging mirror and the spherical surface can be refracted to the bottom in the secondary optical dodging mirror to form a light concentrating area, and the light concentrating area is located at the bottom of the square taper. Therefore, the light concentrating effect can be improved effectively, and the sunlight can be uniformly refracted to a bottom chip.

Description

technical field [0001] The invention relates to a solar photovoltaic power generation module, in particular to an optical homogeneous mirror structure for completely refracting sunlight to the chip at the bottom of the photovoltaic power generation module. Background technique [0002] Solar photovoltaic power generation technology allows us to enjoy the clean and renewable energy provided by the sun, and the light-receiving components in the solar high-power concentrating photovoltaic power generation module adopt a secondary optical homogeneous mirror structure, which can reduce the allowable error angle of the solar tracking system from 0.2 degrees Increase to 1.2 degrees, and increase the utilization rate of the solar chip area to almost 100%, to achieve the purpose of uniform heat dissipation. [0003] Patent application 200810042090.5 describes a high-power concentrating non-tracking photovoltaic power generation module, which includes solar cells, a heat dissipation ...
