New ways to take advantage from solar energy and produce hydrogen / Nuevas formas de aprovechar la energía solar y producir hidrógeno

Rey de Castro, Ana 25 September 2017 (has links)
Un grupo de investigadores del Instituto Tecnológico de Israel ha observado que el uso de foto ánodos de Fe2O3 produce una mejora importante en el rendimiento de las celdas fotoelectroquímicas. Las mejoras están basadas en el uso de láminas muy delgadas de Fe2O3 que mejoran la eficiencia en el transporte de carga. La elección de Fe2O3 está basada en su estabilidad en agua, su alta eficiencia de absorción de luz, su no toxicidad y su bajo coste. Las celdas fotoelectroquímicas son importantes para la electrólisis del agua y la producción de hidrógeno. / A research group at the Israel Institute of Technology has outlined the use of Fe2O3 photoanodes to enhance the efficiency of photoelectrochemical cells. The improvement is based on the design of extremely thinsheets of Fe2O3, which allow for a more efficient transport of charge carriers, reducing the amount of them that are lost due to recombination. Fe2O3 was chosen as a photoanode material due to its high stability in water, its high light absorption efficiency, the fact that it is non toxic and its low cost. Photoelectrochemical cells are extremely important in order to electrolyse water, hence producing hydrogen,a green fuel.
