  • HYBRID PHOTOVOLTAICALLY ACTIVE LAYER AND METHOD FOR FORMING SUCH A LAYER
    Publication number: 20090065056
    Abstract: A “hybrid” photovoltaically active layer is homogenous (in a direction parallel to the major surfaces of the layer) with respect to film constituents, but is non-homogenous with respect to photovoltaic properties. First regions exhibit high absorptivity, while second regions that are perpendicular to the major surfaces of the layer exhibit a higher carrier mobility. The method for forming the layer includes one or all of chemical vapor deposition, the hollow cathode effect, and high power DC pulsing.
