To provide an inexpensive pigment compound capable of achieving a high photoelectric conversion ratio, accessible without remarkable restriction, a photoelectric conversion element and a solar battery using the same.
The pigment compound is represented by formula (I) (wherein D1 is a group bonded with a nitrogen atom or a group having a basic nucleus; L1 is a single bond or a divalent group consisting of at least one arylene group, an alkenylene group or an alkynylene group; D1 and L1 may be bonded with each other so as to form a ring; A1 is an acidic group; R1 is a heterocyclic group including atoms selected from hydrogen, carbon, oxygen, nitrogen and sulfur, bonded with an aliphatic group, an aromatic group or a carbon atom; and R2 is a heterocyclic group bonded with a hydrogen atom, an aliphatic group, an aromatic group or a carbon atom).
