Dye sensitised solar cells (DSSC) have potential to be a low cost technology for renewable energy. Component materials used in DSSCs are in relatively low cost. It would be desirable if the devices would be manufactured by low cost continuous processing techniques as well. A mesoporous TiO2 film is a major component of working electrode, which is formed from a slurry containing nano TiO2 particles. The wet chemistry process allows the DSSC devices to be printed. A large scale screen printing line (10 meter long) has been established at Monash University recently, which can continuously print DSSC modules up to 30 x 30 cm in size on plastic, glass and steel substrates. DSSC devices made on plastic substrates have particular attractions due to their flexibility, lightweight, easy to handle during transport and installation. There are technical difficulties in fabricating DSSCs on plastics, resulting in lower conversion efficiency compared to their glass based counterparts. Different measures have been investigated to tackle these issues, but more need to be done especially in low temperature processing of TiO2 working electrodes on plastics.
