A charge separation heterojunction structure which uses a fullerene polymernfilm as a part of its constituent materials and which may be used to produce a solarncellor a light emitting diode superior in durability, physical properties of electrons andneconomic merits. The heterojunction structure is such a structure in which an electron-donatingnelectrically conductive high-polymer film and an electron-accepting fullerenenpolymer film are layered between a pair of electrodes at least one of which is lightntransmitting. In forming the layers, the fullerene polymer film is identified using innparticular the Raman and Nexafs methods in combination so that upper layers arenformed after identifying the polymer film. |
