Nickle Oxide Based Bulk Heterojunction Flexible Solar Cells

Abstract:

This paper presents an efficient flexible organic solar cell with room temperarure sputtered and highly conductive nickle oxide (NiO) thin film as hole transporting layer. The strcture of this kind of devices is PET/ITO/NiO/P3HT: PCBM [regioregular of poly (3-hexylthiophene):(6,6)-phenyl C61 butyric acid methyl ester] /Al. On the study of characteristics of Nickle oxide thin film, such as sputtering temperature, thickness, and oxygen proportion, we found that NiO with 10 nm and sputtered at room temperature shows the best photovoltaic properties. The highest power conversion efficiency (PCE) of 3.26% and 2.5% were achieved on glass substrate and flexible substrate individually. The device photovoltaic properties were discussed in terms of the band diagrams and series resistance of the devices. Also the properties of nickle oxide thin film on different conditions were investigated too.
