TiO2 fibers made on a cotton template outperform TiO2 particles in photovoltaic device tests
Department: Science & Technology
Keywords: dye-sensitized solar cells, photovoltaics, titanium dioxide

Electrodes made from hollow titanium dioxide fibers outperform ones made from solid spherical TiO2 particles in photovoltaic device tests, according to a study by researchers in Switzerland and Iran (Nano Lett. 2010, 10, 1632). Dye-sensitized solar cells (DSCs) typically incorporate a photoanode fabricated from a film of interconnected, porous, spherical TiO2 nanoparticles that are coated with dye molecules. DSCs . . .
