Researchers discover new technologies for organic solar cells Xinhua News Agency, Wuhan, December 22 (Reporter Li Wei) Researchers at the Wuhan University Advanced Research Institute have proposed a new layer-by-layer blade coating technology that not only enables higher film performance, but also can be applied to large-area preparation of organic photovoltaic devices. This discovery of new technologies for organic solar cells was recently published online in the international energy industry's top journal, Energy and Environmental Sciences. Organic solar cells have attracted widespread attention due to their unique advantages such as low cost, light weight, and the ability to be made into translucent and flexible devices. In previous studies, researchers have analyzed the cost of industrial applications of organic solar cells in Wuhan and compared the cost of organic solar cells with other new solar cells. The results show that organic solar cells have great advantages in terms of cost. In order to overcome the shortcomings of heterojunction active layer processing, the research team of Wuhan University Jiejie successfully prepared vertical phase separation, charge transfer and collection efficiency by layer-by-layer solution method using two different processes: spin coating and blade coating. Active layer structure. According to Yan Jie, the active layer structure prepared by the new layer-by-layer solution method not only exhibits comparable and even higher photoelectric conversion efficiency, but also shows better device thermal stability. They have successfully developed non-fullerene organic solar cells with an efficiency of more than 10% using the developed layer-by-layer coating technology. This work provides a new coating technology for large-area preparation of organic solar cells, which will have great application prospects. The Biodegradable Straw was made of fully biodegradable materials. The fully biodegradable materials are derived from plant fibers and plant starches. The production process does not produce toxic and harmful substances, and the use process will not convert toxic and harmful substances. After use, the product can be directly composted and converted into organic fertilizer to return to nature to promote plant growth.
