http://www.freepatentsonline.com/8030185.html

This patent is from the Industrial Technology Research Institute of Taiwan and teaches a metal/semiconductor nano-hetero structure for absorbing solar energy and converting light energy into chemical energy, hydrogen energy, or electrical energy. Claim 1 reads:

1. A fabricating method of a nano-hetero structure, comprising:

fabricating at least a nano-semiconductor base; and

adding a metal ion solution into an amine solvent containing the nano-semiconductor base such that a plurality of metal nanoparticles are grown on a surface of nano-semiconductor base to form the nano-hetero structure.
