Claim Text:
1. A photoelectric conversion element comprising: 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, wherein the photoelectric conversion layer comprises a condensed polycyclic hydrocarbon which contains at least 5 benzene rings, of which a total number of rings is 6 or more and which contains no carbonyl group, and wherein the condensed polycyclic hydrocarbon comprises a condensed polycyclic hydrocarbon represented by any one of general formulae (1) to (8), (13), (14), (16), and (17): (in general formulae (1), (8), (13), (16) and (17), R 1 to R 16 each independently represent a hydrogen atom or a substituent; in general formulae (2) and (3), R in general formulae (4) and (6), R in general formulae (5) and (7), R in general formula (14), R wherein the electron-blocking layer comprises a compound A including a residue after removal of at least one group of Ra (in general formula (A), Ra 1 to Ra 8 each independently represent a hydrogen atom, a halogen atom, an alkyl group, an aryl group or a heterocyclic group, which may further have a substituent; R a9 represents an alkyl group, an aryl group or a heterocyclic group, which may further have a substituent; and Xa represents a single bond, an oxygen atom, a sulfur atom, an alkylene group, a dialkylsilylene group, an alkenylene group, a cycloalkylene group, a cycloalkenylene group, an arylene group, a divalent heterocyclic group or an imino group, which may further have a substituent) and having a glass transition point (Tg) of 200° C. or more.
