Au electrodes made of PbSe quantum dot layer. PbSe quantum dots are produced in a chemical solution. The quantum efficiency of 130%, is a band gap of solar cells is 0.72eV, and energy is 3.44eV (wavelength approximately 360nm) UV region of the ratio of photons. It was alleged that can calculate, MEG is about 2.6 times times the bandgap, or about 1.9eV above (wavelengths around 653nm) of visible light can also occur.
