Since their discovery, conjugated polymers have attracted tremendous attention because of their suitability in a wide range of promising electronic, optical, and electrochemical applications such as organic thin-film transistors, and organic photovoltaic cells (OPVs). In OPVs, it is believed that an ideal polymer should have a high mobility and a low band-gap. We reported thienylenevinylene-based polymer, which has high mobility and relatively low band-gap. Thienylenevinylene moieties increase the degree of coplanarity of the conjugated polymer backbones due to the curtailment of steric interactions on successive aromatic rings. To make lower band-gap polymer, we synthesized donor-acceptor copolymer. The absorption spectrum of a new copolymer cover the range between 400 and 800 nm, and its optical bandgap is 1.56 eV. In this presentation, we will discuss on the performance of OPVs fabricated by a new semiconducting polymer. |
