Abstract

We employed ultrasonic spray deposition method for production of high quality FTOthin film TCOs to be employed in a silver embedded grid type and monolithic typedye sensitized solar modules. Produced films exhibited dense and crystallinestructure with homogeneous coverage on solar glass substrates. Obtainedresistivity and light transmission values of FTO are comparable to commerciallyavailable FTO coated glasses used widely in the industry. After optimization ofthe chemistry and deposition conditions, 10x10 cm sized glass substrates couldbe produced for large area photovoltaic modules. Produced FTO films were used toconstruct monolithic type and parallel type dye sensitized solar modules.Monolithic modules yielded 1.61% active area efficiency value. In order toenhance the active area of the parallel type modules, silver grid lines wereembedded in glass substrate and FTO coating was deposited on the lines. Due tothis effective design, we achieved 2.42% efficiency on the total area of the55x55 mm sized module compared to 2.90% active area efficiency, proving thatthis design is suitable for enhancing efficiency values of parallel type dyesensitized solar modules.
