US researchers say that nanotechnology can produce conductive inks, making it possible to print cheap and stable solar cells on clean surfaces. Prof. Richard L. Brutchey, a chemist at the University of Southern California, said that nanocrystals are only 4 nanometers in size. A pin can hold 250 trillion nanometer crystals at the bottom of the pin. Nanocrystals can flow through liquid solutions, so it is like printing newspapers. Solar cells can also be printed. Liquid nanocrystalline solar cells are cheaper to manufacture than single crystal cells, but the latter is not as effective in converting sunlight into electricity. In the past, organic molecules were attached to the nanocrystals to keep the latter stable and prevent the latter from sticking to each other. However, organic molecules also caused crystal insulation and affected the conductivity of the crystal. A report released by the University of Southern California on Wednesday states that Prof. Brutchey and postdoctoral researcher David H. Webber have developed a new surface covering nanocrystals. This not only results in good crystal stability, but in fact bridges the nanocrystals. Better transmission current. According to the researchers, since this is a low-temperature process, solar cells manufactured by this method can be printed onto plastic surfaces without having to worry about melting, not necessarily on the surface of glass, and thus can be manufactured anywhere. Flexible solar panels. Prof. Brutchey stated that the commercialization of this technology will take several years, but they are very clear about the future direction of the technology in integrating this technology into next-generation solar cell technology.
