Patent ID: 8030118

Claim:
A method for producing a single crystal silicon solar cell, the solar cell including a transparent insulator substrate and a single crystal silicon layer arranged over the transparent insulator substrate and acting as a light conversion layer, the method comprising at least the steps of: preparing the transparent insulator substrate and a crystal silicon substrate having a first conductivity type; implanting at least one of hydrogen ions and rare gas ions into the single crystal silicon substrate through an ion implanting surface thereof to form an ion implanted layer in the single crystal silicon substrate; closely contacting the single crystal silicon substrate and the transparent insulator substrate with each other via a transparent electroconductive adhesive while using the ion implanting surface as a bonding surface; curing and maturing the transparent electroconductive adhesive into a transparent electroconductive film, to bond the single crystal silicon substrate and the transparent insulator substrate to each other; applying an impact to the ion implanted layer to mechanically delaminate the single crystal silicon substrate thereat to leave a single crystal silicon layer; forming a diffusion layer having a second conductivity type in the single crystal silicon layer, which conductivity type is different from the first conductivity type, in a manner that a p-n junction is formed in the single crystal silicon layer; and forming an electrode on the single crystal silicon layer.
