Abstract
A structure and a method of the solar cell efficiency improvement by the strain technology are provided. The solar cell has a first surface and a second surfaces which at least a gasket is disposed thereon for supporting the solar cell and being the axle whiling stressing. The method includes the steps of: (a) applying at least a stress on the first surface; (b) generating a supporting force on the second surface; and (c) generating at least a strain in the solar cell. In addition, the present invention also includes a method involving a step of: (a) applying a mechanical stress to the solar cell; (b) generating a tension in the solar cell by at least two materials having different lattice constants; or (c) generating another tension in the solar cell by a shallow trench isolation filler, a high tensile/compressive stress silicon nitride layer and a combination thereof.
