Abstract
Dye-sensitized solar cells (DSSCs) based on double layered photo-anode geometry incorporating transmitting and absorbing layers of titanium dioxide which are activated with a known stable C106 dye have been fabricated. The photovoltaic parameters have been studied both indoors under standard reporting conditions (AM 1.5G at 100 mW/cm(2) irradiation) as well as under the actual harsh outdoor conditions in Jeddah, Saudi Arabia, one day each month for a full one year period. Outdoor performance of cell exhibited the power conversion efficiencies of over 9% with a small degradation over a one year period. Reasons for degradation in the performance of cell parameters have been discussed in the text.
