Problems solved by technology

However, no matter whether it is a point-focus or line-focus concentrator, the light intensity at the focal spot is uneven, and the middle is strong and the two sides are weak.
Uneven light intensity will lead to uneven operating temperature of the solar cell and a decrease in the fill factor of the cell, resulting in a decrease in the efficiency of the entire system
Therefore, in order to obtain a relatively uniform light intensity distribution on the surface of the solar cell, the cells can only be arranged at the center of the focal spot, which cannot make full use of the concentrated light at the focal spot, resulting in a waste of energy

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] A concentrated photovoltaic receiver with a secondary reflector, including a light-transmitting tube 1, a battery assembly 3, and an insulating liquid 2, and also includes a secondary reflector 4, and the secondary reflector is arranged above or below the light-transmitting tube , the battery assembly is formed into a prism and arranged in the light-transmitting tube, and the insulating liquid is arranged in the light-transmitting tube.

[0016] The number of sides of the prism can be 2 or 3 or more, such as 10, 15 or 20.

[0017] The cell components forming the prismatic side surfaces can be formed by direct connection of solar cells or by connection of solar cells to the substrate 5 .

[0018] The geometric shape of the secondary reflector is a V-shaped groove composed of 2 surfaces, a U-shaped groove composed of 3 surfaces, or a V-shaped groove or U-shaped g...

Abstract

The invention discloses a photovolatic concentrating receiver with a secondary baffle board, comprising a light-transmitting tube, a battery assembly, insulated liquid and a secondary baffle board. The secondary baffle board is arranged above or below the light-transmitting tube; and the battery assembly forms a prismatic shape and is arranged in the light-transmitting tube in which the insulated liquid is arranged. In the invention, primary light-focusing light which is arranged around focus spots and is not irradiated on the battery assembly is reflected into the light-transmitting tube by using the secondary baffle board and the battery assembly which is arranged in the light-transmitting tube and forms a prismatic surface can fully receive partial light-focusing light, so that full utilization of the light-focusing light can be realized. Meanwhile, the insulated liquid flowing through the light-transmitting tube can effectively cool a solar battery and is beneficial to ensuring the high-efficiency work of the solar battery.

Description

technical field [0001] The invention belongs to the technical field of concentrated photovoltaic power generation. It relates to a concentrated photovoltaic receiver. Background technique [0002] Solar photovoltaic power generation technology is a solar energy utilization technology that directly converts the sun's light energy into electrical energy. It has many advantages such as cleanness, safety, no noise, simple structure, and easy installation. Although solar photovoltaic power generation has attracted much attention, due to the high cost , has yet to fully enter the market. Since concentrating solar cells usually have higher efficiency than ordinary solar cells, one of the effective ways to reduce the cost of solar cell power generation is to use concentrating solar cells to reduce the battery area required for a given power and use cheaper concentrating solar cells. Optical devices to partially replace expensive solar cells. However, no matter the concentrator wi...
