Influence Of Substrate

Indium tin oxide was prepared using RF magnetron sputtering at different substrate temperature. The morphological and electrical properties were investigated. Morphological properties were observed by atomic force microscopy. Electrical properties were measured using standard two-point probe measurements. The result shows that the average roughness and peak to valley value are highest at high substrate temperature. The watershed analysis shows that the total grain boundaries are highest at the substrate temperature of 200°C. The lowest resistivity value of 9.57×10-5 Ωcm is obtained from ITO nanocolumn deposited at substrate temperature of 200°C. The improvement of morphological and electrical properties as transparent conducting oxide was observed from ITO nanocolumn deposited at substrate temperature of 200°C.

Abstract Aluminum doped ZnO thin films (AZO), which simultaneously transmit light and conduct electrical current, are widely applied in photovoltaic devices. To achieve high performance AZO thin films, the effects of RF magnetron sputtering conditions on the optical and electrical properties of the films has been explored. The optimized AZO thin films exhibit strong (002) orientated growth with hexagonal wurtzite structure. The minimum resistivity of 0.9Í10-3 Ω·cm, the highest carrier concentration of 2.8Í1020 cm-3, the best Hall mobility of 22.8 cm2·(V·s)-1 and average transmittance above 85% can be achieved at the optimum deposition condition of 0.2 Pa, 120 W and 200 °C. Considering the single parabolic band model, the bandgap shift by carrier concentration of the films can be attributed to the Burstein-Moss effect. The results indicate that RF magnetron sputtered AZO thin films are promising for solar cell applications relying on front contact layers.
