A thin paper, translucent, flexible "low cost" "plastic" can "power", and the photoelectric conversion rate reached 17.3%. This research is the “Research on Organic and Carbon Nanomaterials for Energy Conversion and Storage†completed by Professor Chen Yongsheng, School of Chemistry, Nankai University, who just won the second prize of the National Natural Science Award on January 8. Solar power is a kind of green, environmentally friendly and sustainable clean energy. "For example, if the sunlight reaches the ground, if it is completely converted to 1 kilowatt per square meter, if the efficiency is 20%, then 200 watts per square meter, if calculated according to 6 hours a day, it is 1200 watts per square meter, which is 1.2 degrees. Electricity can be used to drive cars for about 10 kilometers. The normal city window is about five or six square meters. If there is equipment that can generate solar power on the window in the future, you can have tens of kilometers of electric energy for electric vehicles every day. "Chen Yongsheng said. Unlike traditional photovoltaic power generation using inorganic materials such as crystalline silicon, organic solar cells are one of the effective ways to solve environmental pollution and energy crisis. They are light, soft, translucent, can be printed on a large area at low cost, and are environmentally friendly. Far superior to traditional solar cells, it is considered to be a new generation of green energy technology with significant industrial prospects. European scientists have predicted that if organic solar power reaches the same level of power generation, the cost of inorganic solar energy is about 0.2 euro per square meter, and the cost of organic solar energy is as low as 0.03 euro per square meter. Chen Yongsheng said, "Traditional photovoltaic power generation uses inorganic materials such as crystalline silicon, which is expensive to manufacture and consumes a lot of energy; and carbon is a very cheap material. This organic material is soft, flexible, and colorable. It will be integrated in the future. Chemical, wearable devices, automotive surfaces, etc. can be applied. " Last summer, the layered organic solar cell materials and devices designed and prepared by Chen Yongsheng's team with high efficiency and broad spectrum absorption characteristics achieved a 17.3% photoelectric conversion efficiency, which once again refreshed the photoelectric conversion efficiency of organic / polymer solar cells reported in the literature. World record. This achievement has made organic solar cells a big step towards industrialization, and has been recognized by the world, reported by the internationally renowned academic journal "Science". The BBC reported on the latest achievements of Chen Yongsheng ’s team: “Chinese scientists have recently developed a carbon material-based alternative that can replace costly silicon-based solar cells. This scheme uses carbon-based materials as the basis. The plastic film as the active layer can efficiently convert solar energy into electrical energy, so it can be prepared by convenient and cheap printing technology and can be used together with the exterior of the building. " Chen Yongsheng said, "In the field of organic solar cells, it is one of the few fields where we Chinese are in a leading position. At the same time, we have our own core materials and completely independent preparation technology, although we still have a lot of work to do. However, we are fully capable of providing the country with independent and internationally leading complete technical solutions in this green energy competition.
