Estimating the term…
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.
A method of producing a thin-film single-crystal device by utilizing a thin-film single-crystal, which comprises the steps of:
A solar cell module with flexibility comprising a photovoltaic element having a thin-film single-crystal as at least one portion thereof, wherein a direction in which the module is inherently apt to flex is different from a direction in which the thin-film single-crystal is most apt to cleave.
A solar cell module with flexibility comprising a photovoltaic element having a thin-film single-crystal as at least one portion thereof, wherein at least one portion of a region of the module having the thin-film single-crystal is subjected to plastic deformation, and a direction of the plastic deformation is different from a direction in which the thin-film single-crystal is most apt to cleave.
A method of producing a solar cell module with flexibility comprising a photovoltaic element having a thin-film single-crystal as at least one portion thereof, which comprises arranging the thin-film single-crystal in such a manner that a direction in which the module is inherently apt to flex is different from a direction in which the thin-film single-crystal is most apt to cleave.
A method of producing a solar cell module with flexibility comprising a photovoltaic element having a thin-film single-crystal as at least one portion thereof, which comprises a step of subjecting at least one portion of a region having the thin-film single-crystal of the module to plastic deformation, wherein the plastic deformation is carried out in such a manner that a direction of the plastic deformation is different from a direction in which the thin-film single-crystal is most apt to cleave.
