AFM and PL spectra revealed their good film-forming properties, high thermal and morphological stability, and good photoluminescence characteristics. The double-layer solution-processed OLEDs (ITO/PEDOT:PSS/EML/BCP/LiF:Al) fabricated using CThnT and CThnCT as the emissive layer and BCP as the electron-transporting and hole-blockinglayer, exhibited stable green to orange electroluminescence (λEL = 536–592

and characterized four organicdyes (9, 10, H1, H2) based on a 3,6‐disubstituted carbazoledonor as sensitizers in dye‐sensitized solarcells. These dyes have high molar extinction coefficients and energy levels suitable for electron transfer from an electrolyte to nanocrystalline TiO2 particles. Under standard air mass 1.5 global (AM 1.5 G) solar irradiation, a device using dye H4 exhibits a short‐circuit
我们已合成和表征四种有机染料(9,10,H1,H2)的基础上一个3,6-二取代的咔唑供体作为染料敏化太阳能电池的增感剂。这些染料具有高的摩尔消光系数和能级,适于电子从电解质转移到纳米TiO 2颗粒中。在标准空气质量1.5全局(AM 1.5 G)太阳辐射下,使用染料H4的设备的短路电流密度(J sc)为13.7 mA cm -2,开路电压(V oc)为0.68 V,填充因子(FF)为0.70,计算出的效率为6.52%。在相同条件下,该性能可与基于N719(7.30%)的参考电池相媲美。在60°C下浸泡1000小时可见光后,总效率保持在初始值的95%。
