摘要:
A method of manufacturing a laminated substrate is provided. The method includes: forming an oxide film on at least a surface of a first substrate having a hardness of equal to or more than 150 GPa in Young's modulus, and then smoothing the oxide film; implanting hydrogen ions or rare gas ions, or mixed gas ions thereof from a surface of a second substrate to form an ion-implanted layer inside the substrate, laminating the first substrate and the second substrate through at least the oxide film, and then detaching the second substrate in the ion-implanted layer to form a laminated substrate, heat-treating the laminated substrate and diffusing outwardly the oxide film.
摘要:
There is disclosed a method for producing a single crystal silicon solar cell comprising the steps of: implanting hydrogen ions or rare gas ions into a single crystal silicon substrate through an ion implanting surface thereof to form an ion implanted layer in the single crystal silicon substrate; conducting a surface activating treatment for at least one of: the ion implanting surface of the single crystal silicon substrate; and a surface of the transparent insulator substrate; bonding the ion implanting surface of the single crystal silicon substrate and the transparent insulator substrate to each other, in a manner that the surface(s) subjected to the surface activating treatment is/are used as a bonding surface(s); applying an impact to the ion implanted layer to mechanically delaminate the single crystal silicon substrate thereat to leave a single crystal silicon layer; and forming a plurality of diffusion regions having a second conductivity type at the delaminated surface side of the single crystal silicon layer, in a manner that a plurality of first conductivity-type regions and a plurality of second conductivity-type regions are present at the delaminated surface of the single crystal silicon layer. There can be provided a single crystal silicon solar cell as a see-through type solar cell, including a thin-film light conversion layer made of single crystal silicon having a higher crystallinity.
