Abstract

The application of UV irradiation processes are successfully proposed for the first time in the fabrication of both of the two plastic electrodes in flexible dye solar cells (DSCs) and modules. For the realization of the photo-electrode, a customized TiO2 paste formulation and UV processing method was developed which yields 134% (48%) performance enhancement with respect to the same (binder-free) paste treated at 120 degrees C. UV treatment induces both complete removal of organic media and more efficient charge collection. Significantly, highly catalytic platinized flexible counter-electrodes are also obtained via UV photo-induced reduction of screen-printed platinum precursor pastes based on hexachloroplatinic acid. Using both UV-processed electrodes, a fully plastic DSC is fabricated with a conversion efficiency of 4.3% under 1 Sun (semitransparent) and 5.3% under 0.2 Sun (opaque). Performance is within 10% of the efficiency of a glass-based DSC prepared with the same materials but with conventional high temperature processes. The material formulations and processes are simple, and easily up-scaled over large areas, even directly and simultaneously applicable to the preparation of both the photo-and counter-electrode on the same substrate which enabled us to demonstrate the first module on plastic realized with a W series interconnection.
