    摘要： Embodiments of the invention provide a thin single crystalline silicon film solar cell and methods of forming the same. The method includes forming a thin single crystalline silicon layer on a silicon growth substrate, followed by forming front or rear solar cell structures on and/or in the thin single crystalline silicon film. The method also includes attaching the thin single crystalline silicon film to a mechanical carrier and then separating the growth substrate from the thin single crystalline silicon film along a cleavage plane formed between the growth substrate and the thin single crystalline silicon film. Front or rear solar cell structures are then formed on and/or in the thin single crystalline silicon film opposite the mechanical carrier to complete formation of the solar cell.

    摘要： Solar cells are provided with carbon nanotubes (CNTs) which are used: to define a micron/sub-micron geometry of the solar cells; and/or as charge transporters for efficiently removing charge carriers from the absorber layer to reduce the rate of electron-hole recombination in the absorber layer. A solar cell may comprise: a substrate; a multiplicity of areas of metal catalyst on the surface of the substrate; a multiplicity of carbon nanotube bundles formed on the multiplicity of areas of metal catalyst, each bundle including carbon nanotubes aligned roughly perpendicular to the surface of the substrate; and a photoactive solar cell layer formed over the carbon nanotube bundles and exposed surfaces of the substrate, wherein the photoactive solar cell layer is continuous over the carbon nanotube bundles and the exposed surfaces of the substrate. The photoactive solar cell layer may be comprised of amorphous silicon p/i/n thin films; although, concepts of the present invention are also applicable to solar cells with absorber layers of microcrystalline silicon, SiGe, carbon doped microcrystalline silicon, CIS, CIGS, CISSe and various p-type II-VI binary compounds and ternary and quaternary compounds.

    摘要： A method of preparing a clean substrate surface for blanket or selective epitaxial deposition of silicon-containing and/or germanium-containing films. In addition, a method of growing the silicon-containing and/or germanium-containing films, where both the substrate cleaning method and the film growth method are carried out at a temperature below 750° C., and typically at a temperature from about 700° C. to about 500° C. The cleaning method and the film growth method employ the use of radiation having a wavelength ranging from about 310 nm to about 120 nm in the processing volume in which the silicon-containing film is grown. Use of this radiation in combination with particular partial pressure ranges for the reactive cleaning or film-forming component species enable the substrate cleaning and epitaxial film growth at temperatures below those previously known in the industry.
