A New Buffering Layer of Photovoltaic Solar Cells

This paper presents a new buffering layer(nickle oxide thin film) of organic solar cells. Nickle Oxide(NiO) thin film is a good alternative of hole tansporting layer. We investigates the film from physical and electrical aspects, such as morphology, deposition temperature, thickness etc. We find that the optimum fabrication conditions are: room temperature deposition, 10nm of thickness, and 30% oxygen proportion. The device strcture is Anode/NiO/P3HT[regioregular of poly(3-hexylthiophene)]: PCBM[(6,6)-phenyl C61 butyric acid methyl ester] /Al. And the best power conversion efficiency of device we got with NiO buffering layer is 2.49%, which is hundred times of ones without NiO buffering layer.

Photovoltaic Solar Cells

An efficient flexible organic solar cell was presented. The highest power conversion efficiency (PCE) of 3.2% 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. Room temperarure sputtered and highly conductive nickle oxide (NiO) thin film as hole transporting layer in the cells. 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.
