Stacked photoelectric conversion device and method for producing the same
To provide a stacked photoelectric conversion device and a method for producing the same, in which an interlayer is provided between photoelectric conversion layers to obtain an effect of controlling the amount of incidence light, and carrier recombination at an interface between the interlayer and a semiconductor layer is decreased to enhance photoelectric conversion efficiency.The stacked photoelectric conversion device of the present invention comprises a plurality of silicon-based photoelectric conversion layers having a p-i-n structure stacked, wherein at least a pair of adjacent photoelectric conversion layers have an interlayer of a silicon nitride therebetween, the pair of the photoelectric conversion layers are electrically connected with each other, and a p-type silicon-based semiconductor layer constituting a part of the photoelectric conversion layer and contacting the interlayer contains a nitrogen atom.
