abstract = "Four metallated conjugated oligothiophenes, S-1, S-2, S-3 and S-4, with platinum(II) aryleneethynylenes as the electron-rich building block were synthesized to investigate their physicochemical and photovoltaic properties. These small molecules possess fairly low-lying HOMO energy levels which match with the LUMO energy level of the electron acceptor PC70BM ([6,6]-phenyl-C71-butyric acid methyl ester). Using the simple process of spin-coating solution fabrication technique, S-1:PC70BM (1:4, w/w) based organic solar cells exhibiting a high V oc of 0.913 V, with a PCE value of 0.88\% were developed. In contrast, the OSC device based on S-2:PC70BM (3:7, w/w) displayed a higher PCE of 1.59\% with a higher J sc value of 5.89 mA cm-2. The device based on S-4:PC70BM (1:4, w/w) exhibited a PCE value of 1.56\%, with a V oc of 0.917 V.",
