Such methods are particularly useful in laser scribing a cadmium telluride thin-film based photovoltaic device.

    Abstract: The invention provides a method of manufacturing a monolithic thin-film photovoltaic cell or module with enhanced output voltage as high as 100 V or higher in a single microelectronic process without connecting in series a plurality of premanufactured solar cells. The method consists of forming a plurality of adjacent individual TSCs arranged on a common transparent substrate in the longitudinal direction of the substrate. Each TSC consists of a pair of PV cells having PIN and NIP structures, respectively, with substantially coplanar position of a P-doped layer of one of the cells with respect to an N-doped layer of another cell of the pair. A tunnel junction is formed between the cells of the pair by overlapping P-doped and N-doped layers in the area near the common transparent substrate.

  • Patent number: 8071414
    Abstract: The present invention relates to a method of fabricating an organic photovoltaic device with improved power conversion efficiency by reducing lateral contribution of series resistance between subcells through active area partitioning by introducing a patterned structure of insulating partitioning walls inside the device. According to the method of the present invention, since the lateral contribution of series resistance between the partitioned subcells is minimized and each subcell works independently, there is no interference phenomenon against the current output of each subcells. As such, the function of a charge extraction layer with high conductivity can be maximized. Thus, the method of the present invention can be effectively used in the fabrication and development of a next-generation large area organic thin layer photovoltaic cell device.
