Organic solar cells (OSCs) have attracted great research interests due to several advantages, such as light weight, the compatibility on flexible substrates and the possibility of tailoring band gaps. One of the approaches for highly efficient OSCs is to use donor-acceptor type conjugated polymers for tuning band gaps to obtain desired properties such as larger absorption spectrum. However, a great number of those polymers have the limitation of solubility, which is one of the important factors when designing organic semiconductors. Therefore, conjugated polymers as active materials are needed to be highly soluble in common organic solvents for better processability and device performance. For that reason, an alkyl-thienylenevinylene derivative as highly soluble electron donor was introduced with a solubility-functionalizable electron acceptor. Measurements such as DSC, UV-vis and CV, and those characterizations including thermal and optical properties will be discussed. |
