A study on the characteristics of $TiO_2$ electrode in dye-sensitized solar cells using electrospray method

정전분무법을 이용한 염료감응형 태양전지의 $TiO_2$ 박막 특성에 관한 연구

Dye sensitized solar cells(DSC) have been very economical and easy method to convert solar energy to electricity. DSC can reach low costs in future outdoor power applications. However, to commercialize the DSC, there are still many shortages to overcome such as a low efficiency in a large size DSC. In this study, DSCs were fabricated by an electrospray coating method for the $TiO_2$ thin film. They were compared with DSCs prepared by conventional coating methods. We conducted an experiment to obtain the optimized parameters of voltage, flow rate, incident angle and distance in the electrospray method. After we manufactured $TiO_2$ film using that way, we could analyze the characteristics of DSC through SEM, UV curve, EIS.
