Solar energy (SE) research is relevant today, especially as far as dye-sensitized solar cells (DSSC) are concerned, which are third-generation devices. The prospect of their future development lies in the creation of architectural and interior-integrated panels, flexible and portable devices for SE conversion. Examining the properties of their components and their mutual impact is crucial for improving the efficiency of DSSC and moving away from the standard cell design.
In this work, we investigated dielectric properties of photoanodes (PhA) for DSSC. The influence of a dye on dielectric properties of PhA is shown. By measuring dielectric properties in the samples, we obtained dielectric permittivity and dielectric loss tangent that ranged from –50 to 150 °C and from 10-1 to 106 Hz.
Our results make a significant contribution towards a better understanding of the influence that the dye has on dielectric properties of PhA and can serve to develop new efficient composite materials for new-generation photoelectronic devices.
