In the presence of electroactive anions, n-type Si surfaces coated with positively charged surface attached reagents show substantial improvements in stability as compared to naked n-type Si anodes. Modification of photoanodes with cationic polymers can lead to improved electrode stability, with photoelectrochemical efficiences comparable to other methods of electrode modification with molecular reagents. Advantages include convenience of preparation and facile characterization of the polymer, rapid deposition of films onto a variety of surfaces, and stability of the electrostatically bound ion systems. Application of improved coating techniques may prove useful in the design of stable photoelectrochemical cells in aqueous solution.
