Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, in particular to a lightweight integrated PVT photovoltaic component. Background Art

[0002] Photovoltaic modules are components that can convert solar energy into electrical energy. They make full use of solar energy and do not produce any wastewater, waste residue or other pollutants during the conversion process. They are of great significance in alleviating the energy crisis and environmental pollution.

[0003] Traditional photovoltaic modules only have the function of power generation. During the power generation process, the glass surface can reach a high temperature of 70-80 degrees. The temperature characteristic of photovoltaic modules is that under the same irradiation conditions, the higher the temperature, the lower the photoelectric conversion efficiency. This part of 70-80% of the heat energy is not effectively utilized.

[0004] However, the highest photoelectric conversion rate of solar cells currently used on the market is only 16%, and the effective utilization rate of solar energy is low. Most of the solar energy is converted into heat energy and then lost, causing a huge waste of energy, increasing the cost of solar energy utilization, and limiting the promotion and application of solar photovoltaic power generation technology.
