摘要
A method of fabricating a wafer-size photovoltaic cell module includes defining an integrated cellular structure of a light converting monolateral or bilateral junction diode in an epitaxially grown detachable layer including a first deposited metal current collecting terminal of the diode. The method also includes laminating onto the surface of the processed epitaxially grown detachable layer a film of an optical grade plastic material resistant to hydrofluoric acid solutions. The method further includes immersing the wafer in a hydrofluoric acid solution causing detachment of the epitaxially grown silicon layer laminated with the film, and polishing the surface of separation of the detached epitaxially grown layer and forming a second metal current collecting terminal of the diode by masked deposition of a metal at a temperature tolerable by the film.
