The hydrophilic nature of the polyacetylene is shown to enhance the interfacial contact and electrical coupling between hydrophilic CdS and the polymer. The hydrophilicity of the polymer was modified toward hydrophobicity by anion exchange in order to adequately layer the hydrophobic poly (3-hexylthiophene) by spin coating, power-conversion efficiency 1.18% (AM1.5, I=100 mW/cm(2)).
