Dying to live: Subtle molecular structural variations in two zinc porphyrin dyes significantly influence the performance of dye-sensitized solar cell devices. By utilizing the dyes in combination with a cobalt-based redox electrolyte, a high power conversion efficiency (PCE) under simulated solar light is achieved. When using spiro-OMeTAD as the hole-transporting material in solid-state solar cells, the highest PCE for such a device until now is observed.
