<p><P>PROBLEM TO BE SOLVED: To provide an organic thin film solar cell which has excellent photoelectric conversion efficiency and durability (in particular, durability under the presence of oxygen), and has less deterioration in the photoelectric conversion efficiency even when a cell size is increased. <P>SOLUTION: In the organic thin film solar cell which includes a first electrode, a second electrode, and a photoelectric conversion layer arranged between the first electrode and the second electrode, the photoelectric conversion layer contains a polymer having a structural unit represented by the formula (I). (In the formula, X<SP POS="POST">1</SP>and X<SP POS="POST">2</SP>represent N or CR<SP POS="POST">3</SP>, and at least one of X<SP POS="POST">1</SP>and X<SP POS="POST">2</SP>is N; Z<SP POS="POST">1</SP>and Z<SP POS="POST">2</SP>represent S or Si, and at least one of Z<SP POS="POST">1</SP>and Z<SP POS="POST">2</SP>is S; and R<SP POS="POST">1</SP>and R<SP POS="POST">2</SP>represent a monovalent substituent; R<SP POS="POST">1</SP>and R<SP POS="POST">2</SP>may be bonded to each other to form a ring; and R<SP POS="POST">3</SP>represents a hydrogen atom or a substituent.) <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
