Title:
MANUFACTURING METHOD FOR ORGANIC PHOTOELECTRIC CONVERSION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2012/111784
Kind Code:
A1
Abstract:
A manufacturing method for an organic photoelectric conversion element equipped with a pair of electrodes, with an active layer containing a polymer compound between the pair of electrodes, said polymer compound having a structural unit represented in formula (1). An active layer formed from a solution containing the polymer compound, a first solvent, and a second solvent different from the first solvent, whereby an organic photoelectric conversion element that exhibits excellent photoelectric conversion efficiency can be manufactured. (1) (In the formula, Ar1 and Ar2 are the same or different, and represent a trivalent aromatic group. Z represents -O-,-S-,-C(=O)-,-CR1R2-,-S(=O)-,-SO2-,-Si(R3)(R4)-,-N(R5)-,-B(R6)-,-P(R7)- or -P(=O)(R8)-. R1, R2, R3, R4, R5, R6, R7 and R8 are the same or different, and represent a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, an alkylthio group, an aryl group, an aryloxy group, an arylthio group, an arylalkyl group, an arylalkoxy group, an arylalkylthio group, an acyl group, an acyloxy group, an amide group, an imide group, an imino group, an amino group, a substituted amino group, a substituted silyl group, a substituted silyloxy group, a substituted silylthio group, a substituted silylamino group, a monovalent heterocyclic group, a heterocyclic oxy group, a heterocyclic thio group, an arylalkenyl group, an arylalkynyl group, a carboxyl group or a cyano group. n represents 1 or 2. When n is 2, the two Zs may be the same or different.)
