Solution-Processed Cu2Se Nanocrystal Films with Bulk-Like Thermoelectric Performance

Abstract Thermoelectric power generation can play a key role in a sustainable energy future by converting waste heat from power plants and other industrial processes into usable electrical power. Current thermoelectric devices, however, require energy intensive manufacturing processes such as alloyi...
