Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a building material photovoltaic module integrating photovoltaic, light and heat. Background technique [0002] The burning of fossil fuels, coal, and other non-renewable resources to generate electricity produces harmful carbon emissions that are released into the atmosphere. These carbon emissions have a negative impact on the environment, greatly increasing global warming and causing natural disasters. Therefore, it is necessary to reduce carbon emissions by using more renewable energy sources such as wind and solar to generate electricity. [0003] People and businesses have been drawn to the virtues of solar energy, which is not only good for the environment but also generates its own electricity. Solar energy, or photovoltaics, has been used for decades by harnessing sunlight to generate usable electricity. In actual photovoltaic applications, it is found that under ...

AI Technical Summary

Problems solved by technology

In actual photovoltaic applications, it is found that under standard conditions, the conversion efficiency of solar crystalline silicon cells is about 12% to 17%, that is, about 80% of the solar energy irradiated on the surface of the cell will be converted into heat energy. For silicon cells, Every time the working temperature rises by 10°C, the photoelectric conversion efficiency drops by 6% to 8%. Therefore, it is necessary to take measures to cool down the photovoltaic panels and recycle excess heat.
