Luminescent thin film silicon device.

摘要

The present invention relates to a luminescent device comprising, on a conducting substrate (1), an amorphous-silicon layer (2) doped so as to be conductive, at least one upper part (3) of which has been made porous by anodization and oxidized. The substrate can be a metal, a single-crystal silicon wafer doped and metallized on its rear face, a conductive polymer, a small glass plate coated with a transparent conductive layer on the side where the amorphous silicon is deposited, etc. <IMAGE>
