Diamond wide bandgap
Web1 day ago · Wide-bandgap (wide-Eg) perovskites with bandgaps over 1.65 eV have great potential in constructing tandem solar cells (TSCs), however, they still suffer from large open-circuit voltage (VOC) deficits. WebSemiconductors with wider bandgaps can operate at higher temperatures; therefore, diamond power devices have the capability to operate at higher ambient temperatures than the other materials. In addition, a higher electric breakdown field results in power devices with higher breakdown voltages.
