PROBLEM TO BE SOLVED : To provide a single crystal silicon solar cell employing a thin film light conversion layer in order to utilize material silicon effectively and exhibiting excellent conversion characteristics while suppressing impairment due to irradiation with light as a see-through type solar cell applicable as a window material for lighting of housing. SOLUTION : The process for manufacturing a single crystal silicon solar cell comprises a step for injecting hydrogen ions or rare gas ions into a single crystal silicon substrate, a step for forming a transparent conductive film on the surface of a transparent insulating substrate, a step for performing surface activation of the ion injection surface of the single crystal silicon substrate and/or the transparent conductive film surface on the transparent insulating substrate, a step for sticking the ion injection surface of the single crystal silicon substrate and the surface of the transparent conductive film on the transparent insulating substrate, a step for stripping the single crystal silicon substrate mechanically by applying an impact to the ion injection layer thus obtaining a single crystal silicon layer, and a step for forming a pn junction in the single crystal silicon layer.
