Information
The maximal theoretical efficiency of the conventional one-junction solar cells is about 32%. The limit is related to the fact that in a conventional cell a photon can lead only to a single charge separation. This means that if the photon has more energy than the bandgap, this extra energy is lost as heat. In semiconductor quantum dots (QD) it has been found that a single light quantum can form multiple electron-hole pairs – excitons. This effect could drastically increase the above 32% limit in efficiency of the solar cells. The process is ultrafast and involves an initial coherent stage.
