Abstract:Counter electrodes of Carbon Aerogel with Silver Sulfide Structures (CA/Ag 2 S) were synthetized by cathodic deposition and solid vapor reactions. Their optical and electrical properties were determined, and they were tested as counter electrodes in dye-sensitized solar cells instead of the conventional Pt. It was found that the Ag 2 S presence improves the optical and electrical conductivity of the counter electrodes. However, the impedance electrochemical spectra indicated increased resistivity (ERS) and cha… Show more
