Abstract We present a large area trifunctional glass prototype combining a photo-electrochromic (PEC) device and an organic light-emitting diode (OLED), interfaced through a properly designed electronic control system. A 12×17 cm2 PEC glass-on-glass module was realized, containing four dyesensitized solar cells (DSSCs) and a central electrochromic (EC) section deposited on the same glass panel. All PEC layers are screen-printed, including the mesoporous electrochromic layer, obtained from a custommade tungsten paste. DSSCs show an efficiency of 2.4%, while the coloration efficiency of the EC section reaches a value of 40 cm2C−1 at 700 nm. A 10×8 cm2 transparent white OLED was also realized, designed and tailored in order to unbalance the emission of light, i.e. maximizing the bottom emission. The efficiency of large area OLED section reaches 8 cd A-1 in the operative conditions and without light outcoupling enhancement systems. The OLED device is clamped on the back of the PEC module and all sections are electrically connected to an external electronic control system. The energy collected by the DSSCs is stored in supercapacitors and used when requested, either applied to the EC section to produce a light shading effect in the daytime, or to the OLED for illumination at night.

结合光伏发电、照明和动态遮光控制的大面积自供电半透明三功能装置

摘要 我们提出了一种大面积的三功能玻璃原型，它结合了光电致变色 (PEC) 器件和有机发光二极管 (OLED)，通过适当设计的电子控制系统进行连接。实现了 12×17 cm2 PEC 玻璃上玻璃模块，包含四个染料敏化太阳能电池 (DSSC) 和沉积在同一玻璃板上的中央电致变色 (EC) 部分。所有 PEC 层都是丝网印刷的，包括从定制的钨膏中获得的介孔电致变色层。DSSC 的效率为 2.4%，而 EC 部分的着色效率在 700 nm 处达到 40 cm2C-1 的值。还实现、设计和定制了 10×8 cm2 透明白色 OLED，以不平衡光发射，即最大化底部发射。大面积OLED部分的效率在没有光输出耦合增强系统的工作条件下达到8 cd A-1。OLED 器件夹在 PEC 模块的背面，所有部分都与外部电子控制系统电连接。DSSC 收集的能量存储在超级电容器中，并在需要时使用，白天应用于 EC 部分以产生遮光效果，或应用于 OLED 以在夜间照明。
