A polydithienosilole derivatives containing a thiophene derivative unit has been successfully synthesized. The polymers were characterized, using various analytical techniques including differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), cyclic voltametry (CV), UV-visible absorption spectroscopy, Photoluminescence (PL) spectroscopy, etc. The energy levels of HOMO and LUMO of the materials were also estimated. Polymeric solar cells were fabricated using the synthesized polymer and PCBM as electron-donor and electron-acceptor materials, respectively. characterization results of the polymer-based photovoltaic devices will be presented in detail. |
