摘要:We demonstrate that power recycling is feasible by using a semi-transparent stripped Al electrode as interconnecting layer to merge a white organic light-emitting devices (WOLED) and an organic photovoltaic(OPV) cell. The device is called a PVOLED. It has a glass/ITO/CuPc/m-MTDATA∶V2O5/NPB/CBP∶FIrpic∶DCJTB/BPhen/LiF/Al/P3HT∶PCBM/V2O5/Al structure. The power recycling efficiency of 10.133% is achieved under the WOLED of PVOLED operated at 9 V and at a brightness of 2 110 cd/m2, when the conversion efficiency of OPV is 2.3%. We have found that the power recycling efficiency is decreased under high brightness and high applied voltage due to an increase input power of WOLED. High efficiency (18.3 cd/A) and high contrast ratio (9.3) were obtained at the device operated at 2 500 cd/m2 under an ambient illumination of 24 000 lx. Reasonable white light emission with Commission Internationale De L'Eclairage (CIE) color coordinates of (0.32,0.44) at 20 mA/cm2 and slight color shift occurred in spite of a high current density of 50 mA/cm2. The proposed PVOLED is highly promising for use in outdoors display applications.
