Dye sensitized solar cells (DSSCs) is a new technology which considered to be the third generation of the photovoltaic technology.
DSSCs have multiple advantages such as simple fabrication, low-cost and environment friendly.
Even though the multiple advantages of the DSSCs, the efficiency of the DSSCs still limited due to the complexity of the device.
That’s why DSSC technology is considered to be a preferable research field in which many studies are being conducted to increase the efficiency of the device.
The objectives of this thesis are to prepare dye sensitized solar cells (DSSCs) using titanium dioxide (TiO2) as a semiconducting layer based on eosin Y dye with adding some modifications to the structure of the device.
These modifications include changing the dyeing duration of TiO2 films, preparing a derivative of eosin Y solution acting as a new photosensitizer, changing the pH of the dye solution and adding ZnO blocking layers.
The results showed that dyeing the TiO2 films for 3 hours can lead to a better performance of the assembled DSSC.
In addition, a derivative of eosin Y was prepared by adding phenylhydrazine hydrochloride solution to the eosin Y solution in a molar ration 1:1 which contributed in enhancing the efficiency of the assembled DSSC.
The treatment of the dye solutions with phosphoric acid resulted in better performance in comparison with hydrochloric acid and nitric acid treatment.
The mechanism used in suppressing the recombination of injected electrons with both the redox electrolyte and the oxidized dye is adding ZnO blocking upperlayers which act as a barrier.
By adding the ZnO upper layers, the performance of the DSSC was improved.
