Description

technical field [0001] The invention relates to a photovoltaic cell, in particular to a low-magnification concentrated photovoltaic cell assembly. Background technique [0002] The structure of a general photovoltaic cell is: glass plate + silicon battery. The surface temperature that the solar panel can withstand is about 85°. If the temperature is too high, the circuit will burn out, the function of the silicon plate will be lost, and the power generation efficiency will be reduced. Traditional solar panel heat dissipation mainly relies on radiation heat dissipation and convective heat exchange with air. In a low-power concentrating photovoltaic power generation system, the heat load on solar cells is several times that of ordinary light, and the heat generation will increase significantly. The temperature rise of the cells is inevitable. Therefore, an additional cooling system is needed to assist the battery in cooling and reduce the battery temperature. remain within an...

Problems solved by technology

Although this is simple and effective, after several years of wind and rain and alternating changes in temperature, the silica gel will gradually age, resulting in uneven contact between the silicon cell and the heat sink, which will affect the heat dissipation effect, and then affect the power generation of the system quantity

What's more serious, after the aging of the silica gel, the glass plate and the battery will separate from the radiator, fall and break, causing losses to the photovoltaic power station
