Description

Technical Field

[0001] The present application relates to the field of PVT components, and in particular to a duct-type double-glass high-temperature and high-efficiency PVT component. Background Art

[0002] Solar photovoltaic / thermal (PV / T) technology combines photovoltaic and photothermal to achieve a higher utilization rate of solar energy. The power generation efficiency of crystalline silicon solar cells depends on their operating temperature. Every 1°C increase in temperature will result in a 0.4% to 0.5% reduction in output power. Since more than 80% of the energy reaching the surface of the cell is converted into heat, the operating temperature of the solar cell is usually above 50°C, and even reaches 80°C when the heat dissipation is poor, which will seriously affect the working efficiency of the solar cell. If the photovoltaic panel and the collector are organically combined, a PV / T collector is formed. The collector takes away the generated heat in time through the medium, controls the operating temperature of the solar cell, can provide electricity more efficiently, and the heat taken away is effectively utilized, greatly improving the overall efficiency of solar energy. Compared with photovoltaic and photothermal systems with the same output, it occupies a smaller area.
