Quantum Dot Solar Cells (QDSC)

Solterra Renewable Technologies solar energy solution will compete on a non-subsidized basis with the price of retail electricity in key markets worldwide. Revolutionary 3rd-generation quantum dot solar cells (QDSC) utilizing high-volume synthesis  of quantum dots formulated as the broad-spectrum photon absorber in solar cells and using high-speed roll-to-roll printing technologies can effectively convert solar energy to electricity at less than half the price of competition.


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.
