Problems solved by technology

At present, the most widely used concentrator is the Fresnel lens concentrator in the transmissive type, but there are several deficiencies in concentrating light with the Fresnel lens: ①The light transmittance is low, and the scattered radiation cannot be used; ②Irradiated on the lens The light loss at the top of the threaded ring is serious; ③The light intensity distribution is uneven after the light is concentrated

However, the use of ordinary optical lenses as concentrators will inevitably cause the device to be overweight and oversized due to the large volume of the lens.

Moreover, even though concentrating solar cell modules have a heat dissipation system, due to the high temperature generated by high-power concentrating, it is still a problem that has not been well solved in concentrating photovoltaic power generation.

Some concentrating solar cell modules with good heat dissipation performance are also complicated due to the complex cooling system, which makes the structure of concentrating solar cell modules too complicated and the cost increases
