Conversion of sunlight into useful forms of energy through photovoltaics is one of the most viable and attractive alternative to address the global concerns of energy supply. In this respect, development of new organic materials for organic photovoltaics (OPV) as well as (opto)electronic applications has been an important and rapidly emerging area of research. 

 

Among the many classes of light harvesting (LH) materials, p-conjugated organic small molecules, dyes and pigments have garnered great attention with regard to their high absorption cross-section, facile optical and redox tunability, synthetic versatility, high charge carrier mobilities, low-cost and the possibility of their roll-to-roll processibility. Along these lines, research in our group will be aimed at developing new LH systems based on p-conjugated molecules/dyes for (opto)electronic applications. Some representative examples are presented in brief in the next page.

 

Research in this group will involve extensive organic synthesis and structural characterization of new chromophoric molecules. Furthermore, the work will involve optical spectroscopy such as UV/Vis, fluorescence, emission lifetimes, fluorescence anisotropy, temperature dependence of emission as well as density functional theory (DFT) and TD-DFT calculations.
