La energ\u00eda solar se ha expandido en el mundo por ser energ\u00eda limpia, econ\u00f3mica y adquirible en el tiempo. Durante a\u00f1os se fueron renovando los sistemas de almacenamiento de la energ\u00eda conservada (se dise\u00f1aron decenas de bater\u00edas de diferentes materiales y tipos) e incluso los nuevos modelos de paneles solares han resuelto el problema de la sobrecarga ( en algunos lugares a\u00fan se utiliza el tapar los paneles para impedir que sigan absorbiendo energ\u00eda).<\/em><\/strong><\/p>\n

Por: Esteban Lubochiner (Tebu) \/ Aurora<\/p>\n

El problema que, hasta el momento, nadie pudo resolver es c\u00f3mo acumular energ\u00eda solar de noche (hay vastos lugares donde el sol no aparece sino hasta 6 meses despu\u00e9s). Una startup israel\u00ed vi\u00f3 este inconveniente y dise\u00f1\u00f3 la soluci\u00f3n. A trav\u00e9s del Technion, utilizando \u00f3xido de hierro (peque\u00f1as l\u00e1mina de \u00f3xido) los cient\u00edficos encontraron otra manera de dividir las mol\u00e9culas de agua en hidr\u00f3geno y ox\u00edgeno.<\/p>\n

Con este descubrimiento, la acumulaci\u00f3n de energ\u00eda solar ser\u00eda mucho m\u00e1s econ\u00f3mica dado que se almacenar\u00eda l energ\u00eda solar en forma de combustibles basados en hidr\u00f3geno. \u201cNuestro enfoque es el primero de su tipo\u201d, dice el investigador principal, Profesor Avner Rothschild, del Departamento de Ciencia de Materiales e Ingenier\u00eda.<\/p>\n

\u201cHemos encontrado una manera de atrapar la luz en pel\u00edculas ultra finas de \u00f3xido de hierro que son 5.000 veces m\u00e1s delgadas que una hoja de papel de oficina normal. Esta es la clave que permite lograr una alta eficiencia y un bajo costo.\u201d<\/p>\n

El \u00f3xido de hierro es un material extremadamente barato pero que ha presentado un gran desaf\u00edo en los investigadores para superar las malas propiedades de transporte el\u00e9ctrico. A\u00f1os llev\u00f3 el superar y encontrarle soluci\u00f3n a este problema, dado que el material no sufre descomposiciones ni corrosiones por agua. \u201cNuestra trampa de luz, supera esta desventaja, lo que permite una absorci\u00f3n eficiente de las pel\u00edculas ultra finas en el que los portadores de carga foto generados se recogen de manera eficiente\u201d, dice el profesor Rothschild<\/p>\n

Este m\u00e9todo surgido de los estudios del Technion, dejar\u00eda de lado el uso indiscriminado de combustibles f\u00f3siles y permitir\u00eda capturar el 90% de la energ\u00eda solar en cualquier situaci\u00f3n clim\u00e1tica u horaria. El avance podr\u00eda hacer posible el dise\u00f1o de c\u00e9lulas solares baratas que combinan foto-electrodos ultra finos de \u00f3xido de hierro con las c\u00e9lulas foto-voltaicas convencionales basadas en silicio u otros materiales para producir electricidad e hidr\u00f3geno.<\/p>\n<\/a>
