Abstract
Methods and devices are provided for absorber layers formed on foil substrate. In one embodiment, a method of manufacturing photovoltaic devices may be comprised of providing a substrate comprising of at least one electrically conductive aluminum foil substrate, at least one electrically conductive diffusion barrier layer, and at least one electrically conductive electrode layer above the diffusion barrier layer. The diffusion barrier layer may prevent chemical interaction between the aluminum foil substrate and the electrode layer. An absorber layer may be formed on the substrate. In one embodiment, the absorber layer may be a non-silicon absorber layer. In another embodiment, the absorber layer may be an amorphous silicon (doped or undoped) absorber layer. Optionally, the absorber layer may be based on organic and/or inorganic materials.
