Abstract

A photoelectric conversion element includes a transparent conductive film, a conductive film, and a photoelectric conversion layer and an electron-blocking layer disposed between the transparent conductive film and the conductive film. The photoelectric conversion layer includes a condensed polycyclic hydrocarbon which contains at least 5 benzene rings, of which a total number of rings is 7 or more and which contains no carbonyl group. The electron-blocking layer includes a compound A having a residue after removal of at least one group of Rto Rfrom a compound represented by general formula (A) and having a glass transition point (Tg) of 200° C. or more. The photoelectric conversion element exhibits high photoelectric conversion efficiency and low dark current characteristics even after heating treatment, and can be manufactured with high productivity.
