Semiconductor films prepd. by electrostatic layer-by-layer deposition can be used to fabricate dye-sensitized solar cells after treatment at 150°. However, the resulting photocurrent is less than when the film is sintered at 500°. The difference in short-circuit current is a factor of 2.2 with the Ru-based dye N719 and is 3.5 with the org. dye D5. The photocurrent at a given wavelength is proportional to the light-harvesting efficiency, charge injection efficiency and charge collection efficiency. Sintered films take up >60% more of either dye than un-sintered films and therefore absorb more photons. Electron injection is hindered in un-sintered films due to a conduction band edge potential 100 mV more neg. than in a sintered electrode. Add...
