NOVELTY - The inorganic solar cell comprises a patterned p-type material layer (64f) formed of an inorganic semiconducting material, an intrinsic layer (68f) positioned on the patterned p-type material layer, an n-type material layer (66f) positioned on the intrinsic layer, and an electrode layer (70f) positioned adjacent to the p-type material layer. The p-type material layer has a first set of protrusions and a first set of recessions, and forms a conformal layer on the electrode layer such that the first set of protrusions and the first set of recessions are formed.    USE - Used as an inorganic thin film solar cell.    ADVANTAGE - The inorganic solar cell has increased conversion efficiency, and can be economically and efficiently manufactured with high stability and without additional processing steps and any negative impact.    DETAILED DESCRIPTION - The inorganic solar cell comprises a patterned p-type material layer (64f) formed of an inorganic semiconducting material, an intrinsic layer (68f) positioned on the patterned p-type material layer, an n-type material layer (66f) positioned on the intrinsic layer, and an electrode layer (70f) positioned adjacent to the p-type material layer. The p-type material layer has a first set of protrusions and a first set of recessions, and forms a conformal layer on the electrode layer such that the first set of protrusions and the first set of recessions are formed. The electrode layer has a second set of protrusions and a second set of recessions. A thickness of the intrinsic layer is configured to be less than a magnitude of diffusion length for the inorganic semi-conducting material and a magnitude of drift length for the solar cell. The protrusions of the first and second sets of the protrusions respectively include a variable width providing a non-vertical wall angle, and have a shape consisting of circle, square, rectangle, triangle and polygon. The protrusions and the recessions of the p-type material layer are formed using an imprint lithography template, and are formed by a metal etchant using an imprinting resist as a mask. An INDEPENDENT CLAIM is included for a method of forming an inorganic solar cell.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a method of forming a solar cell design.
