Copper/silver composite mesh transparent electrodes with low reflection for high-performance and low-voltage transparent heaters

摘要

We developed a kind of Cu/Ag composite mesh transparent conductive electrodes (TCEs) with low reflection on glass substrates through a simple and effective method, and successfully applied them to fabricate transparent heaters with high performance. By combining laser direct writing and PVP coating-assisted localized removal of sputtered metal layers, Cu/Ag composite mesh TCEs with excellent optical and electrical properties were efficiently prepared and showed a low average reflectance down to 5.71% while maintaining a high average transmittance of 86.49% and a low sheet resistance of 0.43 Omega/sq. The transparent heater based on the as-obtained Cu/Ag composite mesh TCE exhibited an effective and rapid heating performance, being confirmed by achieving a steady-state temperature of similar to 131 degrees C within 100 s under an ultralow applied voltage of 0.8 V. A deicing test of an ice block on the transparent heater was also successfully demonstrated. Good optical and electrical properties as well as excellent thermal stability and reliability imply that the transparent heaters based on the Cu/Ag composite mesh TCEs hold great promise in windshield deicing devices.
