Hot carrier solar cells (HCSC) can prevent the thermalization of highly energized photocarriers like electron-hole pairs. This is ensured by a process called energy selective contacts (ESC), in which these photocarriers are extracted from a specific energy level and moved into valleys between energy levels.
