• ][10][11][12][13]. Recently, Yella et al. reported an efficiency of over 12% with a porphyrin-sensitized DSC and a cobalt(II/III) based redox electrolyte [14]. However, many details of the hybrid organic/inorganic interface and the influence of subsequent preparation steps on the device properties, e.g
