Processing of flexible dye sensitized solar cells on plastic substrates

AbstractOne of the major challenges for making dye sensitised solar cells (DSC) on plastic substrates is the difficulty in making good quality porous TiO2 films. Cold isostatic pressing (CIP) is a powder compaction technique that applies an isostatic pressure to a sample in all directions. Nanocrytalline TiO2 films with excellent mechanical stability were prepared on ITO coated plastic substrates in the absence of organic binders by the CIP technique. The morphology and the physical properties of the TiO2 films can be controlled by changing the parameters of the CIP process. The results show that the CIP process can significantly improve the conversion efficiency (CE) of DSC cells. Electrochemical impedance spectroscopy (EIS) analysis indicates a clear correlation between the CE enhancement and the resistivity reduction in TiO2 films after the CIP compression. Porosity reduction and possibly localized joints between some TiO2 nano-particles in the CIP process are assumed to be responsible for the resistivity reduction of the TiO2 working electrode films. This room-temperature processing technique has led to an important technical breakthrough in producing high efficiency flexible DSCs
