Abstract

ZnO film was commonly used as electron transporting layer(ETL) in inverted polymer solar cell (IPSC) due to its excellent performance. Here

rapid thermal annealing(RTA) was applied to treat the ZnO ETL

and IPSCs with the structure of ITO/ZnO/PTB7:PC

BM/MoO

/Ag were prepared. The ZnO films prepared under different annealing conditions were characterized by atomic force microscopy

scanning electron microscopy

X-ray diffraction

UV-Vis-NIR transmission and photoluminescence (PL) spectra. The power-conversion efficiency (PCE) of IPSC using RTA treated ZnO as electronic transporting layer (ETL) is 8.1%

which is 11.26% higher than that of IPSC with ETL treated by traditional thermal annealing. The ZnO films treated by RTA have good crystalline properties

large grain size and rough surface

which decrease the series resistor (

) and increase the short-circuit current density (

)

fill factor (FF) of IPEC.
