Two triphenylamine based Donor-π-Acceptor (D-π-A) organic dyes (TD1 and TD2) whose structures were slightly different from one to another were synthesized. Further, their photophysical and electrochemical properties were examined and their results were presented. TD1 are more suitable material as compared to TD2 for photovoltaics, because of the presence of additional donor on triphenylamine core in TD1. Hence, the present study will pave a way for further molecular design of highly efficient organic dyes for making photovoltaic devices, particularly; dye sensitized solar cells (DSC’s) in future as environmental friendly energy sources.
