Problems solved by technology

[0004] However, the above-mentioned author is limited to thinking on the output characteristics of photovoltaic cells, trying to increase the output power on the external load by tracking the maximum power point to improve the output efficiency of the power generation system. Obviously, in the case where the photovoltaic cells have been determined Under the present situation, the above methods are used to improve the output efficiency of the system, the technical effect is not significant, and there is still no sufficient proof in theory, and it has not been considered from the perspective of the entire energy conversion efficiency.
[0005] In further searches, no literature reports identical or similar to the subject of the present invention have been found

Abstract

This invention relates to a solar photoelectric energy converter including a photovoltaic battery board and an assistant thin water tank, in which , the photovoltaic battery board is formed by composing photovoltaic sensing small wafers on a heat conduction film to make up of a board, said water tank is a cuboid, the top surface of which is made of Al material closely combined with the film of the board, the bottom and four sides are made of stainless steel, inlet / outlet interfaces are set at the cross positions of the two symmetrical sides, the conversion system is connected with the water tank by the interfaces and the conversion system is connected with the photovoltaic battery board.

Description

technical field [0001] The invention relates to a system in the field of energy technology, in particular to a solar photoelectric thermal energy conversion system. Background technique [0002] With the current energy shortage and environmental protection issues becoming more and more prominent, the development and utilization of solar energy as a renewable clean energy has been put on the agenda of industrialization globally. With the progress of material science and basic industry, the theoretical research and practical technology development of how to effectively utilize solar energy have made great progress. However, judging from the current technical status, there are still technical bottlenecks that hinder the efficient conversion and utilization of solar energy. Aiming at the low photoelectric conversion efficiency (10-20%) of the key device of the solar power generation system, the present invention proposes a novel solar-photoelectric-thermal energy converter inven...
