Carbon nanotube bundles were precisely grown atop a p-type silicon wafer that had been treated with catalysts to produce geometries that resemble three-dimensional nano-models to extract more power from the sun. The embedded carbon nanotubes bundles on silicon wafer promise more opportunity for each photon of sunlight to interact with resulting solar cell, as a result of increase of surface area available to produce electricity. The paper discusses morphology of grown nanotubes on silicon wafer along with future prospects of Si-CNTs fabricated solar cells.
