By using a polymer compound comprising a constituent unit represented by the formula (1) and a constituent unit represented by the formula (2) in an organic layer of an organic photoelectric conversion device, photoelectric conversion efficiency can be enhanced:
wherein R
1
represents a hydrogen atom; or a substituent; Y
1
represents an oxygen atom, a sulfur atom or —N(R
3
)—; R
3
represents a hydrogen atom or a substituent; ring Z
1
and ring Z
2
represent each independently an optionally substituted aromatic carbocyclic ring or an optionally substituted heterocyclic ring;
wherein R
2
is different from R
1
and represents a hydrogen atom or a substituent; Y
2
represents an oxygen atom, a sulfur atom or —N(R
3
)—; R
3
represents a hydrogen atom or a substituent; ring Z
3
and ring Z
4
represent each independently an optionally substituted aromatic carbocyclic ring or an optionally substituted heterocyclic ring.
