The Experimental Study on Fresnel Lenses Concentrator Solar Cell Cooling by a Novel Micro Flat Plate Heat Pipe

Abstract:

A novel micro flat plate heat pipe, micro heat pipe array, was used as heat transfer element in Fresnel lenses concentrator solar cell cooling based on its temperature uniformity and the high thermal conductivity. The contrast experiment was carried out in September in Beijing and the cell performance had been studied for difference cooling means, respectively by ordinary fin and "heat pipe and fin". Experimental results show that compared with cooling by the ordinary fin, for "heat pipe and fin" cooling cell the cell temperature is reduced by maximum 8.2% and maintained at about 55°C. The maximum power is 13.21 W, increases by 7.6%. And the photoelectric conversion efficiency improves 6.1%, with maximum efficiency of 24.13%.
