Abstract

Organic solar cells (OSCs) have attracted considerable attention due to their potential for low-cost and large-area solar energy conversion. A lot of work has been undertaken on the electrode buffer layer

which could improve the interface between the electrode and the organic active materials

block exciton to prevent exciton quench at the interface and increase the charge collection

leading to enhanced performance of the OSCs. In this article

the effect of molybdenum oxide (MoO

) buffer layer on the performance of the OSCs with a heterojunction of CuPc/C

was investigated. It was found that the OSCs

with a 10 nm thick MoO

anode buffer layer

showed a little smaller short current

open voltage and power conversion efficiency compared to the control devices without the MoO

anode buffer layer. However

the stability of the devices with a 10 nm thick MoO

anode buffer layer is significantly improved: under uninterrupted illumination

the fill factor

open voltage

and power conversion efficiency of the device without MoO

buffer layer decreases 45% during 20 minute continuous operating

while the fill factor

open voltage

and power conversion efficiency of the device with a 10 nm MoO

anode buffer layer keeps nearly constant

which is attributed to the suppression of the degradation of the interface between ITO and CuPc caused by the uninterrupted illumination

by inducing a MoO

buffer layer into the interface.
