Embodiment 1

[0058] Embodiment 1: hyperboloid reflector

[0059] Such as figure 2 As shown, the hyperboloid reflector is made of glass, and its outline is rectangular. The concave surface is coated with a 100 μm nano-silver layer to reduce the secondary light loss caused by the traditional glass reflector coating on the convex surface. A corner of the reflector is the origin, and the relationship of the curved surface of the hyperboloid reflector in the X-axis, Y-axis and Z-axis directions in the three-dimensional coordinate system is as follows: Z=(X·X+Y·Y) / a, a The range of values ​​is 700-1200mm. In the formula, Z is the height in the Z-axis direction, X is the length in the X-axis direction, and Y is the length in the Y-axis direction. The units of X and Y are millimeters. The values ​​of X and Y of the hyperboloid reflector are related numerical intervals, and the maximum value can be determined according to actual needs, and "·" in the formula represents a multiplication sign. The...

Embodiment 2

[0063] Embodiment 2: Brightening device

[0064] The light intensifier is a conical truncated light intensifier with openings on the upper and lower bottom surfaces. The diameter ratio of the lower bottom surface to the upper bottom surface is 5-10:1. For example, the diameter of the lower bottom surface is 60mm, and the diameter of the upper bottom surface is 6mm-12mm. Among them, the lower bottom surface It is the light inlet, and the upper bottom is the light outlet. The specific size of the light inlet and the light outlet will be adjusted and changed depending on the concentration factor; the material is aluminum alloy, and a 100μm thick silver coating is provided on the inner surface;

[0065] It is also equipped with an open four-legged support for fixed settings. The open four-legged support is composed of a circular opening and a four-legged support extending from one side of the opening. The circular opening is provided with a fixing hole, and the circular The openin...

Embodiment 3

[0066] Example 3: Receiver

[0067] The receiver includes a copper alloy substrate, a group III and five compound semiconductor multi-junction battery, a bypass diode and lead terminals, wherein there is a gold-plated surface on the surface of the copper alloy substrate where the original device is required, and its size depends on the device requirements. The size of the III-V compound semiconductor multi-junction cell is 10.1mm×11.1mm, and the light-receiving area is about 10mm×10mm. The center points of the III-V compound semiconductor multi-junction cell are arranged on the substrate, and the bypass diode and the lead terminals are respectively arranged on the substrate; and the thermoelectric separation layout design is adopted and the production process matched with the copper alloy substrate forms a thermoelectric separation receiver, which reduces the thermal resistance and increases the power generation efficiency; and on the four copper alloy substrates Four holes ar...

Abstract

The invention provides a side type high-power condensing solar module which comprises a floatation glass board, a hyperboloid reflecting mirror, a light adding device, a receiver, a cooling fin set, a breather, a waterproof joint and a module box body. The upper half portion of one side wall of the module box body is provided with an inclined face concaved towards the interior of the box body, and a through hole is formed in the inclined face. The front face of the receiver is arranged on the through hole of the outer side of the inclined face, and the cooling fin set is arranged on the back face of the receiver. The light adding device is arranged on the inner side face of the inclined face, the hyperboloid reflecting mirror is arranged in the box body, and the concave face of the hyperboloid reflecting mirror faces the inclined face. The receiver is parallel to the hyperboloid reflecting mirror, the floatation glass board is arranged at the upper port of the box body, the breather is arranged on the inner side wall of the box body, and the waterproof joint is arranged on the outer side wall of the box body. According to the side type high-power condensing solar module, the light adding effect of the hyperboloid reflecting mirror and the light adding device is utilized, and therefore the side type high-power condensing solar module has the advantages that the light efficiency utilization rate is high, the focal length is short, the radiating effect is good, cost is low, the photoelectric conversion efficiency is high, and losses are few.

Description

technical field [0001] The invention relates to the field of high-power concentrating solar energy equipment, in particular to a side-type high-power concentrating solar module. Background technique [0002] During the Cold War, the former Soviet Union also vigorously researched the improvement of the efficiency of III-V compound semiconductor multi-junction cells and the research on the ground application of concentrating solar photovoltaic systems, which was mainly developed by the Ioffe Institute, the National Research Institute of the former Soviet Union. The host of the project, Dr. Alferov was later awarded the Nobel Prize in Physics in 2000. It can be seen that the development of concentrated solar photovoltaic technology has a long history. [0003] At present, solar modules on the market are divided into: silicon solar modules and high-power concentrating solar modules. Most of the concentrating technology in the field of solar concentrating module technology adop...
