Abstract

The invention discloses a photovoltaic panel with circulating back cooling, which comprises a mounting seat and multiple solar cells, wherein strip-shaped catch basins are vertically and oppositely arranged on the mounting seat; a liquid cooling unit and an air cooling unit are arranged on the mounting seat; the solar cells, the liquid cooling unit and the air cooling unit are connected sequentially from top to bottom; the two strip-shaped catch basins are communicated with the liquid cooling unit respectively; medium flow directions in the liquid cooling unit and the air cooling unit are mutually vertical; and a turning device is arranged below the mounting seat. In comparison with the prior art, the structure is compact, rainwater circulation cooling and cooling air circulation cooling are efficiently combined, the temperature of a solar cell backboard can be effectively reduced, the cooling efficiency is improved on the whole, the power generation efficiency and the service life ofthe solar panel can thus be improved, the series resistance of solar cells is low, the photoelectric conversion efficiency reaches 17.9% to 18.1, the needs of developing new energy sources can be met,an environmental protection concept is also met, and the application prospect is wide.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a photovoltaic panel with circulating back heat dissipation. Background technique [0002] With the increasingly prominent problems of resource shortage and environmental pollution, solar energy, as a clean and renewable energy, has attracted more and more attention from the world. Therefore, the application of solar photovoltaic power generation is becoming more and more extensive. The key component of solar photovoltaic power generation technology is solar cells. In recent years, crystalline silicon solar cells have developed rapidly as the main solar photovoltaic power generation unit. Among them, the front side of solar cells is an important part of crystalline silicon solar cells. On the one hand, through the multi-layer structure in order to achieve the widest receiving line and the least consumption of light reflection. The front side of a conventional commercial cry...
