Abstract

The peeling of a thin-film single-crystal from a substrate is carried out so that the directions of straight lines on the single-crystal surface made by planes on which the single-crystal is apt to cleave are different from the front line direction of the peeled single-crystal. This single-crystal is used in a solar cell and a drive circuit member of an image display element. A method is provided which prevents a decrease in quality and yield of a single crystal layer when it is peeled from a substrate. A flexible solar cell module having a thin film single-crystal layer is made so that its flexing direction is different from the single-crystal's cleaving direction. Thus, a thin-film single-crystal solar cell module having excellent durability and reliability due to a lack of defect or cracking during production and use, and a method for producing the same, is provided.
