Abstract
The present invention is related to a thin-film opto-electronic device and a method of fabricating the same. Particularly this thin film opto-electronic device is fabricated on a Si-containing substrate. The thin-film material is a crystalline semiconductor material. In order to increase the efficiency of this device a porous silicon layer is applied between the thin-film and the substrate. This porous silicon layer has both light reflecting and light diffusing properties thereby giving rise to light confinement in the thin-film.
