Abstract
Poly[(3-thiophenecarboxylic acid)-co-(3-thienyl)-8-(4-octyloxy-4′-nitrostilbenyl) acetate]] (P3TAA-co-P3TDANS) has been synthesized to examined the photosensitizer property on polymer-sensitized solar cells (PSSCs). The resulting copolymer, P3TAA-co-P3TDANS, has good solubility and reasonable molecular weight. The weight-average molecular weight (Mw) and polydispersity of P3TAA-co-P3TDANS were 7.9 × 103 g/mol and 1.73, respectively. PSSCs with a configuration of SnO2:F/TiO2/polymer dye/electrolyte/Pt devices were fabricated by using P3TAA-co-P3TDANS as a photosensitizer. The maximum power conversion efficiency (PCE) of the PSSC based on liquid electrolyte is 0.01% (at 1 sun) for PSSCs.
