Patent ID: 8124865

Claim:
A method of fabricating a wafer-size photovoltaic cell module in an epitaxially grown monocrystalline silicon layer that is eventually detached from a surface of a monocrystalline silicon wafer, comprising: defining an integrated cellular structure of a light converting diode in the epitaxially grown detachable layer including a first current collecting terminal of the diode; laminating onto the epitaxially grown detachable layer a film of an optical grade plastic material resistant to a hydrofluoric acid solution; immersing the wafer in the hydrofluoric acid solution causing detachment of the epitaxially grown silicon layer laminated with the film of optical grade plastic material; and polishing a surface of separation of the detached processed epitaxially grown layer and forming a second collecting terminal of the diode at a relatively low temperature tolerable by the film of optical grade plastic material.
