技術摘要 / Our Technology: |
本案係為一種提昇太陽能電池光電轉換效率的結構及方法。該太陽能電池具有第一及第二平面,第二平面設置至少一墊片,用以支持太陽能電池,該方法包括下列步驟:(a)施加至少一應力於第一平面;(b)產生與該等應力反向的支持力於第二平面;及(c)產生至少一應變於太陽能電池。除了上述方法,本發明尚包括利用兩種不同晶格常數的材料在介面形成晶格張力,以及在太陽能電池特定區域形成類似蓋罩(cap)或其他結構,利用其材料及結構造成之張力而使太陽能電池產生應變。而應變包含單軸向應變、雙軸向應變、拉伸應變、壓縮應變及其組合。利用產生的應變進而提昇太陽能電池的光電轉換效率。
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.
