The bottom surface of the groove of the package seat is provided with a plurality of through holes arranged in a matrix, the heat conduction member includes a plurality of heat conduction blocks corresponding to the through holes, and each heat conduction block is arranged in a corresponding through hole And respectively connected with the solar chip and the circuit board. The invention also relates to a solar cell with such a solar device.

Description

technical field [0001] The invention relates to a solar device and a solar cell comprising the solar device. Background technique [0002] In order to improve the utilization rate of solar energy, concentrating solar cells were used for photoelectric conversion in the past, that is, using a concentrating lens to first concentrate the scattered sunlight, and then project the concentrated sunlight to the solar chip. Although concentrating solar energy can improve the utilization rate of solar energy, concentrating sunlight will inevitably generate high temperature. Therefore, the heat dissipation of concentrating solar cells is particularly important. The heat dissipation performance will directly affect the service life of solar chips and solar cells. The heat dissipation effect of the solar device of the existing solar cell is not ideal, and it is easy to generate local heat concentration effect due to uneven heat conduction. If the heat concentration effect is too obvious, ...
