According to foreign media reports, the Energy Technology and Nanomaterials Innovation Laboratory (CEA-Liten) of the French Atomic Energy and Alternative Energy Agency's Science and Technology Research Department has recently developed a new organic solar cell in cooperation with Toyobo of Japan. The conversion efficiency is in the darkroom. As high as 25%, it has great potential for power generation in indoor environments.
We all know that if the common silicon solar energy on the market is moved to an indoor or low-light environment, people will find that its power generation is greatly reduced, but for organic solar energy, the indoor environment may become its main battlefield.
According to the latest research, the conversion efficiency of the new organic solar energy is as high as 25% under 220 lux illumination with a brightness close to the dark room, compared with the ordinary non-silicon solar energy conversion efficiency of only 16% 60% higher.
There are many manufacturing materials for organic solar energy, and the manufacturing process is mainly based on low-cost and low-energy coating or printing. It can be made into flexible or transparent modules according to different manufacturing processes.
Toyobo has developed a special solar material that can be dissolved in a halogen-free solvent, so scientists can evenly apply the material on the substrate. CEA-Liten and Toyobo also further optimize the solvent and coating technology, in addition to success A small battery is manufactured from a glass substrate, and common plastic polyethylene terephthalate is used as a substrate to produce an organic solar energy of 18 cm2.
It is understood that the module can produce 130 milliwatts of power at an illumination of 220 lux, and the conversion efficiency is significantly higher.
Toyobo said that in the future they will provide materials to solar cell manufacturers, hoping to achieve commercial applications within 3 years. (Author: city)
