Description
Summary:In this work, the extraction of phycoerythrin of red algae from King George’s Island was performed in aqueous media. Among analyzed, best extraction yields were obtained from Palmaria decipiens and Delesseria lancifolia. This phycoerythrin showed adequate characteristics to be used as sensitizer in DSSC (dye sensitized solar cells) with high absorbance values, good stability towards temperature and a satisfactory redox potential value. En este trabajo se realizó la extracción en medio acuoso de ficoeritrina proveniente de algas rojas de la Isla Rey Jorge. Las especies que mostraron mejores rendimientos de extracción fueron Palmaria decipiens y Delesseria lancifolia. Esta ficoeritrina mostró un comportamiento adecuado para su uso como sensibilizador en celdas de tipo DSSC (dye sensitized solar cells), con altos valores de absorbancia, buena estabilidad con la temperatura y adecuado potencial redox.
