Quantum dots help make solar cells cheaper
scholars at the Moscow Institute of Engineering Physics (MEPHI) of the Russian National University of nuclear energy research have developed a new technology for manufacturing quantum dot materials, which is conducive to the development of cheap solar cells that absorb broad-spectrum sunlight
current photoelectric devices are inorganic semiconductor materials based on silicon, which are inefficient, can not process all spectra, and expensive
quantum dots are semiconductor crystals with a size of several nanometers. Changing their size can easily control the properties of solar cells, such as expanding the absorption spectrum. It can also realize various functions by computer, carry out data processing and analysis, and print experimental results. The production of quantum dot condensate is carried out through simple and cheap methods, but in order to obtain high-quality coatings, we must carefully select the production conditions and the types of organic components that connect quantum dots together
Roscoe is also regarded by the international material giants as the best opportunity to speed up the pace of layout. It has developed a technology to replace the ligand at room temperature, which helps to change the distance between quantum dots, so as to control the charge and waste time measuring the efficiency of energy transmission. It is not only used to manufacture photoelectric cells or light-emitting diodes to ensure the very good sealing of equipment, but also to manufacture more complex semiconductor structures, For example, it is used as a semiconductor structure for manufacturing a highly sensitive new generation of sensors
