Scientists discover that desert sand can make solar cells
29/04/2019· At present, most of the silicon materials for solar cells are converted to silicon materials for ultra-high purity semiconductors produced through complicated processes. However, in fact, the silicon data for solar cells does not need such high purity. Therefore, the people of Mianuma and others think that using the inexhaustible sand in the desert instead of the commonly used silica, solar cells can be produced through two simple processes.
