摘要:
A method for manufacturing a poly-crystal silicon photovoltaic device using horizontal metal induced crystallization comprises the steps of forming at least one layer of an amorphous silicon thin film on a substrate, forming at least one groove of which depth is less than or equal to that of the thin film on the amorphous silicon thin film, and horizontally crystallizing the amorphous silicon thin film by forming a metal layer on an upper portion of the groove. Since a crystal shape and a growth direction of the photovoltaic device can be adjusted by the method, a poly-crystal silicon thin film for improving current flow can be formed at a low-temperature.

The present invention relates a method for concentrating a gas by applying a pressure difference to an adsorbent and an apparatus therefor, and particularly, a method for producing an enriched gas in a large amount by introducing a continuous production into every step of the process focusing on productivity rather than concentration of the product gas and an apparatus therefor. The present invention relates to a method incorporating the vacuum swing adsorption method with the pressure swing adsorption method, particularly the rapid pressure swing adsorption method which can continuously produce a desired material in a depressurization step to improve recovery rate of the desired material and productivity and an apparatus therefor. The apparatus according to the present invention is advantageously applied in a small size machine rather than for industrial uses. Particularly, when applied in a small size oxygen concentrator, it can be used in electric home appliances, air conditioners and water purifier, as well as medical products.
