The depletion of fossil fuels and the increase in environmental awareness have led to greater interest in renewableenergy. In particular, solar cells have attracted attention because they can convert an infinite amount of solar energy intoelectricity. Dye-sensitize solar cells (DSSCs) are low cost third generation solar cells that can be manufactured usingenvironmentally friendly materials. However, DSSC photoelectrodes are generally produced by screen printing, which requireshigh temperature heat treatment, and low temperature processes that can be used to produce flexible DSSCs are limited. Toovercome these temperature limitations, this study fabricated photoelectrodes using room-temperature aerosol deposition. Theresulting DSSCs had an energy conversion efficiency of 4.07 %. This shows that it is possible to produce DSSCs and flexibledevices using room-temperature processes.
