Liquid-immersed flat plate photovoltaic component

Abstract

The invention discloses a liquid-immersed flat plate photovoltaic component, which comprises a lower transparent bottom plate, wherein the periphery of the lower transparent bottom plate is fixedly connected with that of an upper transparent cover plate to form a container which contains insulating liquid; a solar cell component is immersed in the insulating liquid and consists of solar cells connected by electrode leads; the solar cell component is fixedly connected with the inner surface of a side wall; and the side wall is provided with an insulating liquid inlet and an insulating liquid outlet. The liquid-immersed flat plate photovoltaic component has high light transmission and therefore can be used for making glass windows, glass curtain walls, glass ceilings or the like of buildings so as to realize perfect combination of the photovoltaic utilization technology and the building. The solar cell is immersed in the flowing insulating liquid so as to be effectively cooled to improve the power generation efficiency, slow down the aging speed, improve the life and reduce the power generation cost. The heat of the insulating liquid after the heat exchange can be further utilized so as to realize combination of power and heat of the photovoltaic system.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation, and relates to a liquid-immersed flat-plate photovoltaic module. Background technique [0002] The efficiency of solar cells decreases with the increase of temperature, and when the temperature exceeds a certain limit, it will cause long-term damage to solar cells. Therefore, maintaining solar cells at lower temperatures will improve the power generation efficiency of the cells and extend the life of the cells. The service life is very important. However, in traditional flat-panel photovoltaic modules, after the solar cells are packaged, the upper and lower surfaces of the cells are covered by adhesives, and the thermal conductivity of the adhesives is generally relatively large, resulting in the actual operating temperature of the solar cells being much higher than the ambient temperature, seriously The actual power generation efficiency of the battery is reduced, and the ...
