Fig. 7. Photocurrent measurements of photobiocathodes without a mediator in 100 mM MES pH 6 and 400 mM KCl at an applied potential of −100 mV vs. Ag/AgCl. (A) Comparison of the performance of PSI-ATTO532 (n = 4) and native PSI (n = 3) at different light intensities; (B) behavior over two hours of 3 electrodes (mean value) prepared with PSI-ATTO532.
