"organic photovoltaic cell... OS photocathode covered with titanium foil and dispersed platinum nanoparticles... onset potential of 1 V versus reversible hydrogen electrode and photocurrent density of -12.3 mA cm-2 at 0 VRHE... record operation stability, retaining 95.4% of the maximum photocurrent for over 30 hours without any noticeable deterioration in the OS. Further, the team tested the module under actual sunlight and was able to produce hydrogen"
