    Thermally and UV Stable Natural Dyes with Potential Use in Efficient Photoelectrochemical Devices

    Mario Alejandro Mejía Escobar*, Franklin Jaramillo*

    Journal of Renewable Materials, Vol.3, No.4, pp. 302-317, 2015, DOI:10.7569/JRM.2014.634121

    Abstract Energy alternatives have been one of the most important research focal areas of the last decade due to the imminent lack of fossil fuels. This motivation has allowed the evolution of the materials science field in areas such as electrochemistry, where high availability, low cost and negligible environmental impact are the desired principal qualities. For this reason, as an example of a photoelectrochemical device, we have proposed the use of natural dyes from 37 agro-industrial wastes in dye-sensitized solar cells. We obtained dyes from red cabbage, radish and roselle wastes with a good stability for More >
