摘要： Photoactive pyrite layers, whose preparation and use represent a commercially highly interesting alternative to materials hitherto in common use. The semiconductor material chiefly used until now, e.g. for solar cells, is silicon. However, its costs of manufacture are too high to allow solar cells to be made at favorable cost. The significance of the disclosure and development of pyrite as a semiconductor material, especially for solar cells, lies in the fact that it is plentifully occurring and cheap, as well as environmentally compatible. Pyrite (iron pyrites, FeS.sub.2) can be used as a photoactive material in solar cells and in optoelectronic components. It is possible to use both naturally occurring pyrite, after a material treatment to improve the photosensitivity, as well as synthetically produced, single-crystal and polycrystalline pyrite.

摘要： A method for preparing a platinum-free chelate catalyst material as an intermediate product for selective electrocatalytic reduction of oxygen includes performing a low-temperature plasma treatment on a powdery form of the transition-metal chelate in a plasma reactor chamber having an inert plasma gas disposed therein. A plasma power, a plasma gas pressure, a plasma initialization and a treatment time of the low-temperature plasma treatment are selected so that molecules of the transition metal chelate are fragmented in the plasma and cross-link in a subsequent chemical reaction so as to form a carbon matrix and retain a basic chelate structure in a surrounding of the transition metal.
