  • Patent number: 8546171
    Abstract: Disclosed is a method of fabricating a thin film solar cell. A separation process (‘P4’ process) of insulating a thin film solar cell from the outside is integrally performed with a transparent electrode patterning process (‘P1’ process) and a metallic electrode patterning process (‘P3’ process). This may reduce the fabrication costs and enhance spatial efficiency as the ‘P4’ process and equipment for the ‘P4’ process are not required.

  • Patent number: 8497199
    Abstract: The present invention relates to a method for fabricating a thin film formed with a uniform single-size monolayer of spherical AZO nanoparticles. Because of its own advantages in cost and transparency, Al-doped ZnO (AZO) transparent conductive film is becoming the most commonly used transparent conducting oxide (TCO) replacement for solar cells. In this invention, a colloidal chemical means is adopted for enabling a chemical reaction between metal salts, water, and polyhydric alcohols at a room-temperature environment, and thereby, a process for fabricating spherical AZO nanoparticles in a diameter ranged between 100 nm to 400 nm according to different parameter configurations can be achieved while controlling the actual Al/Zn ratio to be ranged between 0.1% to 3%. In addition, a dip coating means is adopted for densely distributing the spherical AZO nanoparticles on a substrate into a monolayer close-packed structure.
