Light absorption layer, method of manufacturing same, dispersion liquid, photoelectric conversion element, and intermediate band-type solar cell

Abstract

The present invention relates to a light absorption layer for forming a photoelectric conversion element and an intermediate-band solar cell excellent in quantum efficiency of two-step light absorption, a photoelectric conversion element having the light absorption layer, and an intermediate-band solar cell. The present invention also relates to a method for manufacturing a light absorption layer having an intermediate-band, using a “wet process”, which method can be expected to greatly reduce costs and expand to use for flexible substrates. The light absorption layer of the present invention has an intermediate-band, wherein quantum dots are dispersed in a matrix of a bulk semiconductor having a band gap energy of 2.0 eV or more and 3.0 eV or less.
