ANODIZED NIODIUM OXIDE PHOTOANODE FOR DYE SENSITIZED SOLAR CELL

摘要

A dye sensitized solar cell in which the photoanode includes an anodized niobium oxide (Nb2O5) layer which has been annealed so that the surface exhibits orthorhombic Nub2O5. The anodisation conditions include the use of an electrolyte with low content of water and Fluorine ions at a voltage up to 20V and at a temperature of about 50°C. This results in a Nb2O5 crisscross nanoporous network. The efficiency of the solar cells is enhanced as a result of both generated current and voltage increase.
