Flexible 광전극을 이용하여 제작된 DSSC의 특성연구

Abstract

The dye-sensitized solar cell may have a flexibility like CIGS rather than an efficient function like a silicon cell. And by applying to BIPV, aesthetic and interior elements are also considered. It is expected that the possibility of commercialization can be accelerated through the flexibility of installation and R&D as an element of emergency energy and zero-energy buildings. In this study, the efficiency characteristics of DSSC prepared by manufacturing TiO2 paste for low temperature firing with the existing TTIP were applied to each substrate and then measured. As a result of applying TiO2 paste for low-temperature firing to the existing FTO glass, it showed the highest efficiency of 4.138% in 0.5 mol of TTIP, and was then tested using TiO2 paste with the same 0.5 mol of TTIP added in the experiment. When manufacturing DSSC using ITO film as substrate, the result value was relatively low compared to FTO glass due to the limitation of heat resistance of ITO film. This seems to be due to an increase in charge transfer resistance. As a result of examining the efficiency and electrical characteristics of DSSC manufactured with ITO film substrate, it is determined that it is necessary to stably form a photoelectrode at a lower temperature to maintain a complete flexible form and aesthetics and ensure the performance of a solar cell. If this problem is solved, it will be possible to manufacture with a low unit price and a simple process compared to the existing sputtering method and the roll to roll method containing the same.
