BCP/Ag/MoO3 Transparent Cathodes for Organic Photovoltaics

Thermally evaporable BCP/Ag/MoO3 is demonstrated as a transparent cathode for flexible OPVs. The optical transmittance of Ag film is enhanced by refractive index‐matching layers. BCP/Ag/MoO3 can fulfill the optimum zero‐reflection condition, resulting in high transmittance (75.5%) and low sheet resi...

Zusammenfassung:Thermally evaporable BCP/Ag/MoO3 is demonstrated as a transparent cathode for flexible OPVs. The optical transmittance of Ag film is enhanced by refractive index‐matching layers. BCP/Ag/MoO3 can fulfill the optimum zero‐reflection condition, resulting in high transmittance (75.5%) and low sheet resistance (8.6 ohm/sq). BCP/Ag/MoO3 cathodes could be applicable as general transparent cathodes for flexible organic optoelectronic devices.
