• Low resistivity molybdenum thin film towards the back contact of dye-sensitized solar cell

This paper reports the optimization of the molybdenum thin film electrode as the back contact of dye-sensitized solar cell (DSSC). The molybdenum thin film was grown on the glass substrate by direct current sputtering techniques of which the sputtering power was 150Wat 18 sccm flow rate of Ar. At such sputtering parameters, the Mo film can reach the lowest resistivity of 1.28E−6𝛺 cm at 400 nm thick. And the reflection of Mo membrane was 82%. This value is considered as a very good result for preparation of the back contact of DSSC.

• Enhancement of ethanol-sensing properties of ZnO nanoplates by UV illumination

ZnO nanoplates with hexagonal wurtzite structure were synthesized by hydrothermal treatment. The averagedimension and average thickness of the plates were $\sim 200 \times 400$ and 40 nm, respectively. ZnO nanoplates were deposited on Pt-interdigitated electrodes for the fabrication of gas-sensing devices. The ethanol-sensing properties of the devices were investigated in the dark vs. ultraviolet (UV) illumination. Under the UV illumination, the optimal operating temperature of the devices can be reduced from 237 to 164$^{\circ}$C and the response of the device was increased from 2.8 to 8.5 towards 1500 ppm ethanol vapour.
