Outline of Final Research Achievements

Dye-sensitized solar cell (DSSC), which has lower manufacturing cost, its plentiful resources for DSSC production, has received considerable attention as an alternative to silicon solar cell. But, actual conversion efficiency of DSSC is not high enough (11%) and its durability is poor. In this study, it is confirmed that durability and conversion efficiency of DSSC was kept high performance by maintaining the temperature of DSSC 35℃using the latent heat storage material. And mixing metal fiber materials to latent heat storage material have been investigated in order to enhance the latent heat storage and release processes of the latent heat storage material. As a result, it was found that the effective thermal conductivity of the latent heat storage material was enhanced, and the latent heat release process of the latent heat storage material with metal fiber materials was improved.
