Researchers have come up with a way to turn silicon into a direct bandgap semiconductor, opening the door to the manufacture of ultrathin silicon solar cells.
According to Bredt's rule, double bonds cannot exist at certain positions on organic molecules if the molecule's geometry deviates too far from what we learn in textbooks. This rule has constrained ...
Scientists from the Mainz and Siegen universities have created innovative molecular systems that can store solar energy. The results have been published in the journal Angewandte Chemie.
