New quantum dots may lead to cheaper solar panels
Imedinews reports scientists at Rice University’s Center for Biological and Environmental Nanotechnology have created a new method of producing molecular specks of semiconductors called quantum dots. This new method, which involves making four-legged cadmium selenide quantum dots, is particularly effective at converting sunlight into electrical energy and may result in better, less expensive solar energy. However according to Michael Wong, the study’s principal investigator, there has been no efficient and consistent way to produce the four-legged dots, called tetrapods. Even in the best result, 30 percent of the prepared particles are not tetrapods.
