The reporter learned from the Hefei Institute of Physical Sciences, Chinese Academy of Sciences on February 20th that recently, the team of researcher Wang Zhenyang of Hefei Smart Research Institute of Hefei Institute of Intelligent Devices has developed a solar thermal efficient conversion film. The film material has both high-efficiency light-to-heat conversion capability. At the same time, it has fixed temperature, heat storage and release functions, and has made new progress in solar thermal conversion and thermal energy storage and utilization. Solar photothermal application is one of the simplest, most direct, and most effective ways to use solar energy. However, due to the small and discontinuous energy density of solar energy reaching the Earth, it is difficult to carry out large-scale development and utilization. For a long time, how to convert low-grade solar energy into high-grade thermal energy and enrich solar energy in order to maximize the use of solar energy has been a subject of great international concern. The high light transmittance thin film material that Wang Zhenyang's team has recently produced has excellent light-heat conversion properties and can be widely used in light-heating power generation devices, heat insulation of agricultural vegetable greenhouses and other related fields. At present, relevant national patents have been applied for. To realize the solar thermal conversion and utilization of solar energy, it is required that the thin film material not only has the ability of photothermal conversion, but also has the functions of constant temperature, heat storage and release. The solar thermal-efficient conversion film developed by Wang Zhenyang's team has good cycle performance in thermal energy storage and release. Even if the cycle is repeated more than 100 times, the thermal storage performance will not be attenuated. On the basis of realizing the function of storage and heat release, it is also necessary to control when it stores heat and when it releases heat. Therefore, Wang Zhenyang's team designed a nanocomposite phase change system for the core-shell structure. By adjusting the interfacial interactions, a substantial adjustment of the phase transition temperature of palmitic acid was achieved. The maximum reduction temperature was up to 50°C. This is the largest reported so far. Reduce the amplitude. In addition, Wang Zhenyang's team is guided by waste heat enrichment and efficient conversion and utilization. Through the system integration of the devices, a thermoelectric conversion device based on waste heat power generation has also been developed. Researchers have synthesized a novel composite of graphene and phase change materials by high-temperature evaporation and drying in air at room temperature. The material provides heat flow and superheated electricity to rapidly generate electricity and can light LED lamp beads. This achievement has been reported by the internationally renowned Atlas Scientific website on the theme of “Lighting up small flashlights without batteriesâ€, which has aroused the attention of counterparts.
