Chinese researchers have developed a new type of greenhouse roof that can isolate light. which can allow visible light to enter while converting near-infrared light into electricity.

A group of researchers from the Institute of Environment and Sustainable Development in Agriculture, together with the Chinese Academy of Agricultural Sciences, has developed this new greenhouse structure based on the use of solar spectral separation,
according to China Science Daily.light, with wavelengths ranging from 400 nanometers (nm) to 780 nanometers, is essential for driving the photosynthesis of greenhouse plants. But near-infrared light with wavelengths from 780 nm to 2500 nm contributes
little to plant growth and This can cause overheating inside the greenhouse.Tests by the research group showed that the new solar roof transmits visible light with an all-day transmission rate of 40 percent and converts near-infrared light to electricity at the same time.
Make greenhouse plants grow normally using less cold energy.Electricity generated by the roof, which has a full-day solar panel efficiency of 6.88 percent, can also power the greenhouse's daily operation.
