Research on organic solar cells has in the past decade intensified significantly with a resulting increase in both the efficiency and stability. Polymer and organic solar cells are now viewed by many as being on their way to become a true competitor to the thin film inorganic photovoltaics. The most successful approach to designing low band-gap conjugated polymers is alternation of conjugated electron-rich and conjugated electron-deficient units within the polymer chain. The D-A semiconducting polymers reduce the optical band-gap via intramolecular charge transfer (ICT). We designed and synthesized new copolymer derivatived alkoxyantracene. The copolymer was synthesized by Suzuki coupling reaction. The obtained copolymer was characterized by various spectroscopic methods such as IR and NMR. The thermal, optical and photovoltaics properties of copolymer were also investigated. |
