  Tunability of the photoabsorption and directional charge injection
characteristics of Bodipy-based dye molecules with different carbonyl groups
make them promising candidates for photovoltaic applications. In order to study
the effect of screening in the Coulomb interaction on the electronic and
optical properties of two Bodipy derivatives, we have used linear response
time-dependent and exact exchange hybrid density functional approaches. The
effect of linear and non-linear solvation models on the electrochemical
properties of the dyes has also been discussed.
