conductivity of polymers is always poor compared to anorganic material,
even for conductive polymers like polypyrrole. An alternative are TCO
(transparent conductive oxides) deposited by solvent based techniques. E.g.
INM GmbH in Germany (www.inm-gmbh.de) works on sol gel and spin coating of
such materials (ITO, ATO or AZO). The drawback of such materials is that
you must temper them, but some sol-gel processes work at temperatures as
low as 80°C.
