Patent ID: 8552289

Claim:
A photoelectric conversion device having at least a fullerene derivative as an electron acceptor represented by any one of the following formulae (1A) to (1G): wherein in the formulae (1A) to (1G): R 1 and R 2 are each independently an organic group having 1 to 50 carbon atoms; and R 1 and R 2 do not bind to each other to form a ring, and a compound as an electron donor between a pair of electrodes, wherein the electron acceptor and electron donor are present in a bulk heterojunction; wherein one or more of the organic groups having 1 to 50 carbon atoms are each independently a group represented by the following formula (3): wherein in the formula (3): W is an atom belonging to group 4B of the periodic table; R 3 , R 4 and R 5 are each independently an hydrogen atom, a hydrocarbon group having 1 to 50 carbon atoms, alkoxy or amino; and n is an integer from 1 to 10.
