Strategies towards enhancing the efficiency of BODIPY dyes in dye sensitized solar cells

The goal of this study is to reveal the effect of electron donating and anchoring group of the dye on the electron injection dynamics and photovoltaic performance of BODIPY dye sensitized solar cells. The effect of electron donating properties was studied by choosing methoxyphenyl and triphenylamine (TPA) as electron donor moieties. Therefore, four new BODIPY derivatives were designed and sensitized to achieve these goals. In addition, attachment of the dye to TiO2 was studied by altering the surface morphology of TiO2 with fs laser ablation.
