Abstract

<abstract> <title> <x content-type="archive" xml:space="preserve">Abstract</x> </title> <p>Dye-sensitised solar cells (DSSCs) were fabricated using TiO₂ nanotube array photoelectrodes with natural-dye sensitizers composed of extracts of mango, pumpkin and banana. Conversion of visible light into electricity was accomplished, with a performance comparable to any that has been reported for DSSCs based on TiO₂ nanoparticles. The power conversion efficiencies of cells sensitised with dyes based on mango, pumpkin and banana extracts reached 0·15%, 0·06% and 0·21%, respectively, with short-circuit current densities of 0·44, 0·13 and 0·78 mA cm⁻², respectively.</p> </abstract>
