Title:
POLYMER AND PHOTOELECTRIC CONVERSION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2012/117730
Kind Code:
A1
Abstract:
A photoelectric conversion element 10 has a structure wherein a positive hole transport layer 40, a photoelectric conversion layer 50, and an electron transport layer 60 are sandwiched between a first electrode 30 and a second electrode 70. The photoelectric conversion layer 50 is a bulk heterojunction layer, and fullerene or a fullerene derivative is used as the n-type organic semiconductor. A polymer represented by the following formula (1) is used as the p-type organic semiconductor. R1, R2, R3, and R4 in formula (1) are, independently, either a branched alkyl, linear alkyl, alkyl ester, carboxy alkyl, or alkoxy group. Each X is, independently, either S, O, or N.
