Abstract:
The present invention relates to an improved thin-film solar cell and a method for fabricating a thin-film solar cell having nanostructures incorporated onto an absorber layer and a conductor layer. One of the advantages of the present invention provides an absorber layer of a thin-film solar cell with nanowires having different length for collecting the split charges from the entire portion of the photoactive absorber layer. The electrode structure on the top surface of a thin-film solar cell collects and removes the electrons from the cell without blocking the incident of lights. In addition, a transparent conductive layer provides an assistance to flow out electrons from the solar cell with a minimal loss.
