Photoelectric conversion element and imaging device

摘要

A photoelectric conversion element includes: an electrically conductive thin layer; an organic photoelectric conversion layer containing a compound having a partial structure represented by formula (I) and a fullerene or a fullerene derivative; and a transparent electrically conductive thin layer:;
X represents O, S or N—R10, R10 represents a hydrogen atom or a substituent, Rx and Ry represent a hydrogen atom or a substituent, with at least one representing an electron-withdrawing group, Rx and Ry may combine to form a ring, R represents a bond (—), a hydrogen atom or a substituent, with at least one being the bond, nr represents an integer of 1 to 4, R's may be the same or different when nr is 2 or more, and R's at the 2- and 3-positions or R's at the 5- and 6-positions may combine with each other to form a ring.

1. A photoelectric conversion element comprising:
an electrically conductive thin layer; an organic photoelectric conversion layer; and a transparent electrically conductive thin layer, wherein the organic photoelectric conversion layer contains a compound having a partial structure represented by formula (II) and a fullerene as a mixture:wherein Ra, Rb and Rc each independently represents a substituent; na, nb and nc each represents an integer of 0 to 5; Ra's, Rb's or Rc's may be the same or different when na, nb and nc each is an integer of 2 or more, and each pair of two Ra's, two Rb's and two Rc's may combine with each other to form a ring, provided that na+nb+nc is not 0.
