The film is superior in structure to a traditional solar film solar panel, and can easily pass sunlight into an office space. Applying the film's lighting function to office lighting can not only reduce costs and reduce environmental loads, but also use natural light to understand the true color of objects and reduce stress on the human body.
China has also developed similar lighting films.
As recently as last November, a research team at the State Key Laboratory of Luminescent Materials and Devices at South China University of Technology developed a translucent photovoltaic film with both power generation and thermal insulation functions, which can be attached to window glass to make houses in summer Keep cool and warm in winter.
The research team made organic semiconductor materials into translucent, lightweight films that could turn glass windows into power generation equipment and thermal insulation equipment. This new type of glass film allows visible light to pass through, and cuts off light in the infrared band through a multilayer film structure. At the same time, it absorbs and uses light in the near-infrared band, so it simultaneously meets the requirements of light transmission, heat insulation and lighting power generation.
