ell technology, is an important step.
Up to now, conventional solar cells in the photoelectric conversion, relative to 1 be absorbed photon can only produce 1 electron hole pairs (excitons). Maximum power is available from 1 Exciton depends on the band gap semiconductor material. Therefore, the photon energy is less than the band gap of less effects on the photoelectric conversion, and far greater than the band gap of Photonic energy even absorbed by the semiconductor, and can only be obtain
