We describe photovoltaic cells made from a novel conjugated polyelectrolyte, the lithium salt
of poly (thiophene-3-acetic acid)(PTAA-Li). The aqueous solubility of this polyelectrolyte
allows formation of blend electrodes with a dispersion of the metallic polymer Poly (Ethylene
DiOxyThiophene)(PEDOT). The incident monochromatic photon to current conversion
efficiency (IPCE) of the cells were improved up to 19% by blending PTAA-Li with PEDOT to
modify the ITO electrode, in combination with the low bandgap polymer poly (3-(4 …
