QUANTUM DOT SOLAR CELLS (QDSC)

Photovoltaics describes the ability of a semiconductor materials to change light (photons) into electricity (excitons). A flexible polymer thin-film quantum dot solar cell uses a single layer (or multi-layers) of quantum dots to convert solar radiation to direct current electricity for significant material costs savings over silicon solar modules. When light strikes a quantum dot in a solar cell, excess energy can push an exciton out of its orbit around an atom in the quantum dot, then through a conductive polymer to the electrodes of the cell. The more this reaction occurs successfully, the higher quantum efficiency and wattage production of the system. QDSC have theoretically maximum potential quantum efficiency (PCE) of 65% compared to a maximum 29% PCE using current silicon module technology.
