Solar photovoltaic light condensing device

Abstract

A solar photovoltaic light condensing device is disclosed and comprises a resin package, a light reflection layer, a silicon wafer and a lead pin, wherein the silicon wafer is fixed connected above the light reflection layer in a height direction of the same, the lead pin is connected with the silicon wafer after running through the light reflection layer from a position below the light reflection layer, the light reflection layer is connected with the lead pin in a heat conduction manner, the resin package is fixedly connected above the light reflection layer, and the silicon wafer is embedded in the resin package. The resin package having a spherical surface is used as a light condensing surface, and a light condensation rate can be effectively improved while that the light condensing device can work in all kinds of severe environments can be ensured; the light condensing device is small in size and can be arranged closely, and therefore a conversion rate can be substantially raised while illumination conditions and areas remain the same; the solar photovoltaic light condensing device is simple in structure and easy to manufacture, manufacture cost can be lowered, and requirements for expanded industrial production can be met.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic elements, and in particular relates to a solar photovoltaic light concentrating device. Background technique [0002] With the continuous progress of society, pollution is becoming more and more serious, and the development of renewable and pollution-free new energy has become an inevitable trend of social development. At present, the more common new energy sources are: solar energy, wind energy, water energy, tidal energy, etc., among which solar energy is a relatively common new energy source in daily life, and a photovoltaic cell is a device that converts solar energy into electrical energy. Polysilicon and monocrystalline silicon are usually used to concentrate light into electricity, but the conversion rate of this method is low, generally below 17%, and the production and maintenance costs are high, and installation is inconvenient. [0003] In the prior art, "a concentrating crystalli...

AI Technical Summary

Problems solved by technology

The disadvantages of this technical solution in actual use are: 1. The section of the concentrating surface is trumpet-shaped, which prevents the components from being closely arranged, which greatly reduces the power conversion rate; 2. The single crystal silicon is used as the concentrating device, and the cost is relatively high and not easy to maintain
