Problems solved by technology
In fact, the photoelectric conversion efficiency of current solar cells is only below 20%, and more than 80% of light energy cannot be converted into useful energy.
Therefore, on the one hand, it will cause a lot of waste of solar thermal energy, and at the same time, the thermal energy that is not converted into electrical energy will also cause the temperature of the photovoltaic cell to rise, and the conversion efficiency of the photovoltaic cell will decrease with the increase of the conversion temperature. The heating of photovoltaic cells by heat will cause the conversion efficiency to drop by 3% to 6%.

Embodiment Construction
[0024] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0025] Before describing the various embodiments of the present application in detail, first briefly describe the inventive concept of the present application: in the prior art, solar energy can only utilize part of the thermal energy in the process of generating electricity, and the heat that cannot be utilized will lead to the temperature of the battery panel on the one hand. If it is too high, it will cause energy waste on the other hand. In order to solve this technical problem, the technical solution of the present application proposes: a heat exchange unit 30 is arranged between the solar p...

The invention discloses a solar power generation device based on a split type heat pipe. The solar power generation device comprises a solar cell panel, a temperature difference power generation unit and a heat exchange unit, the heat exchange unit is arranged between the back face of the solar cell panel and the temperature difference power generation unit, and the heat exchange unit is used for absorbing waste heat of the solar cell panel and conducting the absorbed waste heat to the temperature difference power generation unit. Therefore, temperature difference is generated between two ends of the temperature difference power generation unit. On one hand, waste heat is used for thermoelectric power generation, and solar comprehensive utilization efficiency is improved; and on the other hand, the condensed liquid flows back into the evaporation cavity to continuously absorb waste heat of the solar cell panel, the temperature of the solar cell panel is reduced, and the self-generating efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of solar power generation, and in particular relates to a solar power generation device based on split heat pipes. Background technique [0002] With the increasingly prominent energy and environmental issues, solar photovoltaic power generation technology has received more and more attention as a way of utilizing solar energy. In solar photovoltaic power generation technology, in the process of solar photovoltaic power generation, only part of the light energy equal to the bandwidth is absorbed by the battery panel and converted into electrical energy, and the light energy greater than the forbidden band width can only be lost in the form of heat. In fact, the photoelectric conversion efficiency of current solar cells is only below 20%, and more than 80% of light energy cannot be converted into useful energy. Therefore, on the one hand, it will cause a lot of waste of solar heat energy, and at the same tim...
