氟硼二吡啶衍生物於染敏料電池之應用

Abstract

Dye-sensitized solar cells (DSSCs) have attracted much attention in recent year as they offer the possibility of low-cost conversion of photovoltaic energy. Remarkable progress has been made in the field of metal-free organic dyes having high extinction coefficient, which can be achieved from rational design based on the structure-property relationship. Due to its large extinction coefficient, great electrochemical stability, and tunable absorption wavelength BODIPY has been one of the most widely used organic chromophores in various fields, such as sensing, imaging, and solar cell applications. However, the performance of BODIPY-based DSSC is only moderate. For the purpose of understanding the relationship between the electronic structure of BODIPY molecule and its ability to harvest solar energy, we synthesized a series of BODIPY derivatives and examined their potential for DSSC application.
