Tandem organic photoelectric conversion device and solar cell using the same

摘要

[Problem] To provide a tandem-type organic photoelectric conversion element. [Solution] Provided is a tandem-type organic photoelectric conversion element having, stacked therein with an intermediate electrode layer therebetween, at least two subcells which are each sandwiched between a second electrode layer and a first electrode layer formed on a substrate, and which are obtained by sequentially stacking charge transport layers and photoelectric conversion layers. The tandem-type organic photoelectric conversion element is characterized in that: the intermediate electrode layer comprises gold, silver, copper, or an alloy having these as a main component thereof; and a nitrogen-containing compound is included in a substrate-side charge transport layer adjacent to the intermediate electrode layer.
