Hollow optical fiber induced solar cells with optical energy storage and conversion†
Abstract
Hollow optical fiber induced dye-sensitized solar cells are made by twisting Ti wire/N719-TiO2 nanotube photoanodes and Ti wire/Pt (CoSe, Pt3Ni) counter electrodes, yielding a maximized efficiency of 0.7% and good stability. Arising from optical energy storage ability, the solar cells can generate electricity without laser illumination.
