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 the single crystal silicon solar cell are provided to enhance light converting efficiency by using a single crystal silicon layer as a light converting 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 at least one of hydrogen ions and 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 single crystal silicon layer(17) is formed by separating the single crystal silicon substrate. A plurality of first conductive regions(21) and a plurality of second conductive regions(22) are formed in the separated region of the single crystal silicon layer. A plurality of first individual electrodes(23) and a plurality of second individual electrodes(24) are formed in the first conductive regions and the second conductive regions, respectively. A first collector electrode(25) is formed to connect the first individual electrodes to each other. A second collector electrode(26) is formed to connect the second individual electrodes to each other.
