  • THIN-FILM SOLAR FABRICATION PROCESS, DEPOSITION METHOD FOR TCO LAYER, AND SOLAR CELL PRECURSOR LAYER STACK
    Publication number: 20120285522
    Abstract: Method of depositing a TCO layer on a substrate, of depositing precursors of a solar cell and precursors of a solar cell are described. The methods includes DC sputtering a ZnO-containing transparent conductive oxide layer over the substrate, the substrate having a size of 1.4 m2 or above and texturing the ZnO-containing transparent conductive oxide layer, wherein the textured ZnO-containing transparent conductive oxide layer has a root means square roughness of 60 nm or below.

  • METHOD FOR FORMING TCO FILMS AND THIN FILM STACK
    Publication number: 20120255602
    Abstract: A method for controlling surface morphology of a transparent conductive oxide film (TCO) is provided. A substrate is provided as a basis for forming a solar cell. Onto the substrate, a seed layer is deposited. Then, the method includes depositing the transparent conductive oxide film (TCO) above the seed layer. The seed layer is adapted to control the surface morphology of the transparent conductive oxide film. The surface of the transparent conductive oxide film is etched in order to provide a front contact of the solar cell.

  • THIN FILM SOLAR FABRICATION PROCESS, DEPOSITION METHOD FOR TCO LAYER, AND SOLAR CELL PRECURSOR LAYER STACK
    Publication number: 20120012171
    Abstract: Methods for manufacturing a layer stack for a thin-film solar cell and layer stacks are provided. The layer stack includes a transparent substrate having a first refraction index, a transparent conductive oxide layer comprising ZnO, wherein the transparent conductive oxide layer is deposited over the substrate and has a second refraction index, and a further layer, which is deposited between the transparent conductive oxide layer and the substrate, wherein the layer has a third refraction index in a range from the first refraction index to the second refraction index, the layer comprises a metal, and wherein the layer composition has a metal content of 0.5 to 10 weight-%.
