ABSTRACT: Nanocrystalline TiO2 electrodes were silanized and further modified with C60 fullerene films linked by Starburst¿ (PAMAM G0.0) dendrimers of poly(amidoamine), generation 0.0, using a layerby- layer technique into either branched dendritic or linear structures. The resulting films provide organized nanoassembled photoactive surfaces that adsorb in the visible region and offer a high molar extinction coefficient. The linear nanocomposite structure in particular increases the photocurrent efficiency of the polycrystalline TiO2 and decreases the recombination effect, yielding a global collection efficiency of 0.14%.
