Recently, a team of professor Ye Xuanli from South China University of Technology and a team of professor Huang Fei have developed a translucent thin-film solar cell with both power generation and thermal insulation effects. This type of battery film not only has high efficiency photoelectric conversion efficiency, but also its heat insulation effect is extremely excellent. Studies have shown that this kind of solar cell film, which has both power generation and thermal insulation effects, can theoretically save households more than 50% of their electricity consumption, and is expected to greatly improve the energy efficiency of household electricity. Related research has recently been published in the American "Joule" magazine. The team innovatively selected a class of narrow-bandgap non-fullerene receptors with absorption edges extending to 900 nanometers as key components for capturing near-infrared light in the light-absorbing layer. The absorption of near-infrared photons can not only cause the solar cell to generate additional photocurrent, but also endow the battery device with a thermal insulation function. In addition, the ultra-thin metal silver electrode also has a reflection effect on infrared light, which can help to re-reflect part of the near-infrared light back to the light absorption layer, further enhancing the photoelectric conversion efficiency and thermal insulation effect of the device. In order to absorb and utilize near infrared light as much as possible, an optical control layer can also be added behind the silver electrode. Ye Xuanli, a professor at the State Key Laboratory of Luminescent Materials and Devices at South China University of Technology, said that they made organic photovoltaic materials into translucent and lightweight films, making glass into generators and thermal insulators. The thermal insulation rate of this film can be adjusted in the range of 75% to 90%, which is comparable to the high-quality solar thermal insulation film in the market. The team used high-refractive-index materials and low-refractive-index materials to deposit alternately to form an optically controlled microcavity, which can further reduce the infrared light transmittance while maintaining the overall device visible light transmittance unchanged, thereby enhancing the solar cell device again The thermal insulation effect of the film. In addition, under low light intensity, the photoelectric conversion efficiency of this thin film is higher, so it is also expected to use the indoor lights at night to generate considerable electricity. The researchers said that this functional material is still in the early stages of development, but it is expected to open up new space for the application of organic photovoltaic materials. LED downlights are a popular choice for modern lighting designs, offering efficient and effective solutions for both residential and commercial spaces. These small and compact lights are perfect for tight spaces and offer flexibility in installation and design. Mini downlights are even smaller versions, perfect for adding subtle touches of light to specific areas. Adjustable downlights are popular for their ability to change the direction and focus of the light, making them perfect for highlighting artwork or specific features within a space. Trimless versions of downlights offer a minimalist and sleek look, without any visible trim or bezels. With their versatility and energy efficiency, LED downlights are becoming an increasingly popular lighting choice for contemporary and stylish spaces.
