摘要：

We demonstrate high-performance polymer tandem devices (PTDs) combining solar cell (SC) and light-emitting diode (LED), which are fabricated using solution-based techniques for each layer with the use of semiconducting and metallic polymers. The PTD has three terminals-two outer electrodes and an internal common electrode-and functions as a SC and a LED. In the SC mode, the PTD exhibits a reasonable power conversion efficiency of 3.1% under AM 1.5 irradiation conditions, whereas the device functions as a LED with a luminance of 8000 cd/m(2) when applying external bias voltages. A sol-gel processed titanium sub-oxide (TiOx) is efficiently used in the PTDs for carrier transport toward the target electrode. (C) 2012 Elsevier B.V. All rights reserved.
