摘要

介绍了一种高功函数的掺杂钛酸镧的氧化铟透明导电阳极并用其制备了有机光伏器件

详细研究了该材料对器件性能的影响

同时对比了ITO为阳极的器件性能。由于ILTO具有较好的掺杂、较高的透过率和高的有效表面功函数等优异的光电特性

与基于ITO的器件相比

ILTO的有机光伏器件的填充因子、短路电流及功率转换效率均得到了优化与提升

填充因子由61.1%提高到63.5%

短路电流由3.26 mA/cm

提高到5.64 mA/cm

功率转换效率由0.91%提高到1.45%。

Abstract

Two heterojunction organic solar cells based different anode (ITO and ILTO) were investigated to compare the power conversion efficiency (PCE) of organic solar cell (OSCs) in two types of devices with different hole-extracting electrodes. Except for a slight decrease in the open circuit voltage (

)

the OSC with an ILTO anode exhibits an obvious increase in short-circuit current (

) and fill factor (

) as comparing with that of the ITO-anode OSC (

=0.412 V

vs.

0.413 V

=5.64 mA穋m

-2

vs.

3.26 mA穋m

-2

=0.635

vs.

0.611). Sequentially

a power conversion efficiency (PCE) of 1.45% in the ILTO-anode OSC is demonstrated while only 0.91% for the ITO-anode OSC is achieved. The improved PCE in the ILTO-anode OSC is mainly attributed to the energy level alignment between the work function of ILTO and the HOMO level of CuPc

and a higher light transmission in the UV region of the ILTO. Our results indicate that a suitable TCO can effectively improve the performance of organic optoelectronic devices.
