20100089449 | HIGH EFFICIENCY SOLAR CELL AND MANUFACTURING METHOD THEREOF - The present invention relates to a high efficiency solar cell and a manufacturing method thereof. The high efficiency solar cell of the present invention comprises a lower solar cell layer comprising a single crystalline silicon-based pn thin film; an upper solar cell layer stacked on the upper portion of the lower solar cell layer and comprising an amorphous silicon-based pin thin film; and a glass substrate formed on the upper portion of the upper solar cell layer to receive sunlight. According to the present invention, it has an effect that a low-cost high efficiency solar cell can be manufactured. | 04-15-2010 |
20100093126 | METHOD FOR MANUFACTURING A POLY-CRYSTAL SILICON PHOTOVOLTAIC DEVICE USING HORIZONTAL METAL INDUCED CRYSTALLIZATION - 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. | 04-15-2010 |
