NOVELTY - A photovoltaic material is fabricated by forming a crystalline material (105) having worm hole structures overlying a semiconductor substrate (101). The worm hole structures have density distribution from a surface region (107) of the crystalline material to a defined depth within a z-direction of the surface region to form a thickness of material to be detached; and subjecting the crystalline material to a hydrogen plasma species to occupy the worm hole structures of the crystalline material within an interface between the thickness of material and a remaining portion of the substrate.    USE - Method of fabricating a photovoltaic material for photovoltaic device (claimed).    ADVANTAGE - The method provides an improved solar cell, which is less costly and easy to handle.    DETAILED DESCRIPTION - Photovoltaic material fabrication involves:    (A) providing a semiconductor substrate (101);    (B) forming a crystalline material (105) having worm hole structures overlying the semiconductor substrate, where the worm hole structures have density distribution from a surface region (107) of the crystalline material to a defined depth within a z-direction of the surface region to form a thickness of material to be detached;    (C) subjecting the crystalline material to a hydrogen plasma species to occupy the worm hole structures of the crystalline material within an interface between the thickness of material and a remaining portion of the substrate;    (D) providing a glue layer (103) overlying a surface region of the crystalline material;    (E) joining the surface region of the crystalline material via the glue layer to a support substrate;    (F) delaminating the crystalline material from the substrate, while the portion of the thickness of crystalline material remains attached to the support substrate, to cause formation of a textured surface region from the portion of the thickness of crystalline material; and    (G) using the overlying thickness of crystalline material having the worm hole structures on the support substrate for a photovoltaic application.    An INDEPENDENT CLAIM is included for a photovoltaic device (100).    DESCRIPTION OF DRAWING(S) - The figure is a simplified side-view diagram of a photovoltaic device.
