<p><P>PROBLEM TO BE SOLVED: To provide an organic photovoltaic element which can be manufactured easily to enable wet type film forming, does not easily form pin-hole, assures higher stability and results in higher conversion efficiency, against the conventional organic/organic pn type photovoltaic element. <P>SOLUTION: The organic photovoltaic element laminates a transparent electrode 2, an electron accepting organic layer 3 an electron supplying organic layer 4 and a rear electrode 5 on a transparent insulating support material 1. The electron supplying organic layer 4 includes a polymer material, for example, expressed by the following formula. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
