Solar Hydrogen Production Efficiency World Record Broken — “Wormlike” Hematite Photoanode Crushes Old Record A new world record has been set for solar hydrogen production efficiency — the new record-breaking efficiency of 5.3% blows past the previous record of 4.2%, thanks in large part to the development of a new “wormlike” hematite photoanode. The new photoanode was developed by researchers from the Ulsan National Institute of Science and Technology (UNIST) in South Korea, and from the University of Tokyo in Japan. The impressive jump from a record efficiency of 4.2% to 5.3% was achieved by the researchers through the utilization of an entirely new method/different materials — whereas the previous record was set by researchers (from the Ecole Polytechnique de Lausanne in Switzerland) using stable oxide semiconductor photoanodes, the new record was set via the use of the new worm-like hematite photoanode. cleantechnica/2013/09/27/solar-hydrogen-production-efficiency-world-record-broken-wormlike-hematite-photoanode-crushes-old-record/
