Abstract: The present invention discloses a dye-sensitized solar cell structure and a method for fabricating the same. The method of the present invention comprises forming insulation layers on a titanium plate; forming a plurality of titanium dioxide units on the titanium plate each containing a plurality of titanium dioxide nanotubes, wherein each insulation layer is arranged in between two adjacent titanium dioxide units; making the titanium dioxide units absorb a photosensitive dye; forming a transparent conductive film over the insulation layers and the titanium dioxide units; and filling an electrolyte into spaces each enclosed by the transparent conductive film, the titanium dioxide unit, the insulation layers. The present invention not only increases the electron transmission efficiency and photoelectric conversion efficiency but also promote the uniformity of the semiconductor layer.

Abstract: The present invention discloses a grooved dye-sensitized solar cell structure and a method for fabricating the same. The method of the present invention comprises providing a titanium plate having at least one groove; forming insulation layers on the grooves; forming a plurality of titanium dioxide units on the titanium plate each containing a plurality of titanium dioxide nanotubes, wherein each groove is arranged in between two adjacent titanium dioxide units; making the titanium dioxide units absorb a photosensitive dye; forming a transparent conductive film over the insulation layers and the titanium dioxide units; and filling an electrolyte into spaces each enclosed by the transparent conductive film, the titanium dioxide unit, the insulation layers. The present invention not only increases the electron transmission efficiency and photoelectric conversion efficiency but also promote the uniformity of the semiconductor layer.

Abstract: A conveyance arm device for conveying wafers. The conveyance arm device comprises a conducting seat, at least a tweezer, and at least a conducting path. The conducting seat controls and drives the conveying operation of the tweezer. The tweezer comprises a first end and a second end, and a first surface and a second surface between the first and the second ends. The first end of the tweezer is connected to the conducting seat. The conducting film is adhered to the second surface of the tweezer.

Abstract: This invention provides a concave shallow trench isolation structure, and a fabricating method of a shallow trench isolation structure with concave bottom corners. The concave shape of the structure prevents stress centralization, and avoids leakage current or punch through in the source/drain regions.
