Concentration photovoltaic receiver

Abstract

The invention discloses a concentration photovoltaic receiver which comprises a receiver housing, insulating liquid and a solar cell or a cell component, as well as a support plate, wherein the support plate is arranged in the receiver housing, the solar cell or the cell component is arranged on the light-receiving surface of the support plate, a liquid inlet and a liquid outlet are arranged at two ends of the receiver housing, and the insulating liquid is arranged in the receiver housing. The setting of the support plate can improve the surface area of heat radiation of the solar cell or the cell component, when a plurality of solar cells or the cell components are required for large concentration photovoltaic, the rigidity of the solar cells or the cell components can be increased, thereby leading the solar cells or the cell components to be positioned on the same plane and realizing uniform light receiving. Inner fins arranged on the backlight surface of the support plate can further increase the heat radiation area of the solar cell or the cell component and the turbulence degree of the insulating liquid, and enhance the heat transfer effect of the solar cell or the cell component and the insulating liquid.

Description

technical field [0001] The invention relates to a solar receiver, in particular to a concentrated photovoltaic receiver. Background technique [0002] Photovoltaic power generation uses solar cells to convert solar energy into electrical energy, which is a clean energy utilization technology. Due to the high manufacturing cost of solar cells, the popularization of photovoltaic power generation is greatly limited. Concentrating photovoltaic power generation can greatly reduce the cost of photovoltaic power generation by using concentrators and tracking systems, and using small-area concentrating cells instead of large-area solar cells. With the continuous improvement of the efficiency of concentrating cells, the proportion of concentrating photovoltaic power generation in the field of solar photovoltaic power generation is increasing. When concentrating photovoltaic power generation, because the light intensity received by the concentrating cell is tens or even hundreds of ...

Problems solved by technology

The forced convection method can reduce the thermal resistance of the water side and improve the heat exchange capacity of the water side, but correspondingly, the required pump power will also increase, resulting in a large additional power consumption

However, there is nothing that can be done about the thermal resistance of the battery and the partition wall, so the cooling effect of the traditional partition wall is not very good. The temperature of the solar cell is often high, which affects the power generation of the solar cell and shortens the life of the solar cell.
