Abstract:
Processes, relevant for light-induced fuel generation (water photoelectrolysis, CO2 reduction) are shortly reviewed. Stabilization strategies for development of efficient tandem cell structures that are based on non-oxidic semiconductors are presented. The recently introduced nanoemitter concept that involves surface passivation by a nanoporous film is described and first results on light-induced hydrogen generation with p-Si(100) and p-InP(100):2x4 thin films are given. Solar-to-hydrogen efficiencies reach 14% for homoepitaxial InP thin films covered with Rh nanoislands. In the pursuit to develop biologically inspired systems, successful enzyme immobilization at an electrochemically nanostructured Si surface that shows step bunching has been achieved as evidenced by tapping mode atomic force microscopy.
