Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and more specifically to a semi-flexible photovoltaic thermal power generation integrated device. Background Technology

[0002] The efficient utilization of solar energy is an effective way to solve the shortage of fossil fuels. Under full-spectrum sunlight, electrons in the valence band of semiconductors can be excited by high-energy photons with energy greater than the semiconductor band gap. However, in the remaining part of the solar spectrum, low-energy photons with energy less than the semiconductor band gap are wasted, with up to 70% of solar energy being wasted. This waste is converted into harmful heat, reducing the conversion efficiency of solar cells and even shortening their lifespan.

[0003] Conventional photovoltaic-thermal integrated systems involve laying a cooling medium on solar photovoltaic cells. This reduces the temperature of the cells, improving photoelectric efficiency, and also collects and utilizes low-grade heat, achieving comprehensive thermal and electrical utilization of solar energy. However, only about 20% of solar radiation can be converted into electricity; the remaining 80% is released as heat. Collecting this heat is difficult due to its low grade, resulting in complex equipment structures and making large-scale installation impractical.

[0004] Therefore, providing a semi-flexible photovoltaic thermal power generation integrated device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

The heat storage tank is mounted on the base, and the heat collection pipe is connected to the heat storage tank via a flexible hose and a circulation pump mounted on the flexible hose. The semi-flexible photovoltaic panel is electrically connected to the battery.

[0008] By adopting the above technical solutions, the beneficial effects of this utility model are as follows:

[0009] Semi-flexible photovoltaic panels are used to generate electricity by converting the ultraviolet and visible light regions of sunlight into electrical energy, which is then stored in batteries.
