A charge separation heterojunction structure which uses a fullerene polymer film as a part of its constituent materials and which may be used to produce a solar cellor a light emitting diode superior in durability, physical properties of electrons and economic merits. The heterojunction structure is such a structure in which an electron-donating electrically conductive high-polymer film and an electron-accepting fullerene polymer film are layered between a pair of electrodes at least one of which is light transmitting. In forming the layers, the fullerene polymer film is identified using in particular the Raman and Nexafs methods in combination so that upper layers are formed after identifying the polymer film.

Charge separation type heterojunction structure and manufacturing method thereof

Charge separation type heterojunction structure and manufacturing method therefor

A carbonaceous complex structure in which a fullerene thin film is used as a part of the constituent material to improve adhesion between neighboring layers to enable a solar cell or a sensor to be produced to high strength, and a method for manufacturing the carbonaceous complex structure, are disclosed. The carbonaceous complex structure includes a substrate of quartz or glass, on which are layered a carbonaceous thin film and a fullerene thin film Thermal decomposition of an organic compound is used for forming the carbonaceous thin film while a method for vapor-depositing or polymerizing fullerene is used for forming the fullerene thin film

Carbonaceous complex structure and manufacturing method therefor

A method for preparing a carbonaceous complex struture including forming an adherent carbonaceous thin film on a smooth surface of a substrate and forming an adherent fullerine thin film on the thus formed carbonaceous thin film.

A photocatalyst having superior durability; a manufacturing method for the photocatalyst and a method and apparatus for decomposing a gas, where a film which is fullerene-based but different from the evaporated fullerene film is used. The photocatalyst has a fullerene polymer film layered on a substrate. There may be carried fine metal particles on the fullerene polymer film. These fine metal particles are carried by sputtering, evaporation or coating on the fullerene polymer film. The apparatus for decomposing the gas includes a light source and a fullerene polymer film. In effecting gas decomposition, the gas to be processed is contacted with the fullerene polymer film under light illumination.
