    Abstract: The performance of dye sensitized solar cells (DSSCs), sensitized with natural pigments extracted from mango (mangifera indica), carica papaya, moringa oleifera leaves and bougainvillea flower was demonstrated. The photoactive electrodes of the various DSSCs were sensitized with aqueous extract of the natural pigments. The resulting photoelectrodes... Show More

    Abstract: The Effective Medium Theory Model (EMTM) used in this work is based on the assumption that every phase of the matrix is embedded in a homogeneous medium with conductivity keff to be determined self-consistently. It is based on dilute spherical inclusions of one phase embedded in a matrix of a second phase. Several Samples of composite ceramics that... Show More

    Abstract: Glass sample with the composition 1 Li2O • 0.25 Fe2O3• 0.25 V2O5• 1.5 SiO2 has been studied for the usage as a cathode material in solid batteries. Another sample with the previous composition in addition to 5wt. % sulfur as reduced agent to yelled multi-valance Fe and V ions was also studied. Both sulfur-free and sulfur-doped glass samples were su... Show More
