Title:
AN ORGANIC PHOTOELECTRIC CONVERSION ELEMENT COMPOSITION, A THIN FILM CONTAINING SAME, A SOLAR CELL, AN ORGANIC SEMICONDUCTOR POLYMER USED IN SAME, A COMPOUND, AND A METHOD FOR PRODUCING THE POLYMER.
Document Type and Number:
WIPO Patent Application WO/2013/122063
Kind Code:
A1
Abstract:
 Disclosed are an organic photoelectric conversion element composition containing a P-type-N-type coupled organic semiconductor polymer represented by one of formulas (1) to (5) below, a thin film, a solar cell, an organic semiconductor polymer, a compound, and a method for producing the polymer. In the formula, A to A4 represent the bases of P-type organic semiconductor units, and B to B3 represent the bases of N-type organic semiconductor units. L1 to L4 represent bivalent or trivalent linking groups. Here, in each of the formulas, at least one of the bonds represented by -* above and below is, in formula (4), linking directly or via a linking group L4 and (b), and L1 or L 2 and (a). l, n, r, t, u and v are integers from 1 to 1000, m and s are integers from 1 to 10, and p, q, l' and n' are integers from 0 to 1000. However, p and q must not simultaneously be 0.
