FABRICATION METHOD OF SINGLE CRYSTAL SILICON SOLAR BATTERY AND SINGLE CRYSTAL SILICON SOLAR BATTERY

摘要

A method for producing a single crystal silicon solar cell and a single crystal silicon solar cell are provided to enhance crystalline characteristics and conversion efficiency by using a single crystal silicon layer. A transparent insulating substrate(12) and a first conductive type single crystal silicon substrate(11) are prepared. An ion implantation layer(14) is formed by implanting hydrogen ions or rare gas ions into the single crystal silicon substrate. The single crystal silicon substrate and the transparent insulating substrate are attached to each other by using a transparent adhesive(15). A transparent conductive layer(16) is formed by hardening the transparent adhesive. A single crystal silicon layer(17) is formed by separating mechanically the single crystal silicon substrate. A pn junction is completed by forming a second conductive type diffusion layer(22) in the single crystal silicon layer. An electrode(23) is formed on the single crystal silicon layer.
