In this study, we investigated the electrical, optical and structural properties of aluminum-doped ZnO (AZO) thin films by RF magnetron sputtering under different working pressure of 5 -40 mTorr. Optimization of the prepared thin films shows low resistivity of 6.11 × 10 -4 ȍ-cm, mobility of 4.295 cm 2 /V-s and carrier concentration of 3.277 × 10 20 cm -3 at working pressure of 5 mTorr. The maximum transmittance of 98.99 % for wavelengths above 600 nm and Haacke figure of merit (FOM) are 6.44 × 10 -3 ȍ -1 with working pressure of 5 mTorr. These results indicate that AZO thin films are a promising high conductivity transparent electrode scheme for solar cells and various displays applications.

“…TCO films are essential for applications since they constitute a fundamental part in the emerging new generations of photovoltaic devices, including organic solar cells (OSC), require the use of transparent conducting anode materials in order to collect charges and admit light into the active region [5,6]. TCO with high optical transparency in the visible-IR region and high conductivity, such as indium tin oxide In 2 O 3 :Sn (ITO) [7,8], fluorine or antimony-doped tin dioxide (FTO, ATO) [9,10] and aluminum or galliumdoped zinc oxide (AZO, GZO) are still widely applied in electrical and optical devices [11,12]. For ordinary TCO electrodes, typical deposition techniques are chemical and physical vapor deposition, pulsed laser deposition and magnetron sputtering, which demands the rigorous vacuum condition [13][14][15].…”

A novel concept based on the use of solutions containing already qualified crystalline antimony-doped tin oxide SnO 2 :Sb (ATO) nanoparticles has been developed. ATO nanoparticles are decorated by reduced graphene oxide (rGO) through a hydrothermal synthesis method. The electrical and optical properties of the graphene oxide films are investigated systematically. The sheet resistance (R h ) of the ATO-rGO films decreases with the increase in the rGO content in the precursor solution. The R h can be decreased after the ATO-rGO films annealing in the air for 1 h and can be further decreased by depositing Au on the surface of the films. The optimum property of the ATOrGO film shows that the R h is 80 X/h and the transmittance is about 70 %. The ATO-rGO films are used as the anode of the organic solar cells. The anode film impact on the performance of the devices is studied. Finally, the power conversion efficiency (PCE) of the device based on the poly-(3-hexylthiophene): [6, 6]-phenyl C61-butyric acid methyl ester (PCBM) blended is 1.85 %, and the PCE of the device based on the poly-benzo[1,2-b:4,5-b 0 ] dithiophene thieno[3,4-b] thiophene:PCBM blended is 3.4 %.

“…Several techniques can be used for preparing AZO thin films including DC or RF magnetron sputtering [8] , electron beam evaporation [9,10] , pulsed laser deposition [11] , spray pyrolysis [12] , sol-gel processing [13][14][15][16][17][18][19][20][21][22][23] , etc. Among them, the sol-gel process has distinct advantages over other approaches due to its excellent compositional control, homogeneity on the molecular level, simplicity, and lower crystallization temperature.…”

Transparent and conducting Al-doped ZnO thin films with c-axis-preferred orientation were prepared on glass substrate via sol-gel route. The physical and chemical changes during thermal treatment were analyzed by TG-DSC spectra and the crystallization quality was characterized by XRD patterns. The optimized preheating and post-heating temperatures were determined at ~420℃ and ~530℃, respectively. From thermodynamic and kinetics views, we investigated the mechanism of orientation growth with (002) plane parallel to the substrates. The surface morphologies of the films, post-heated at 420℃, 450℃, 530℃ and 550℃, respectively, were observed by SEM micrographs. The film post-heated at 530℃ shows a homogenous dense microstructure and exhibits the minimum sheet resistance of 140 Ω/Sq. The visible optical transmittance of all the films is beyond 90%. In addition, the annealing treatment in vacuum can contribute greatly to the electrical conductivity. transparent conducting oxide, sol-gel method, zinc oxide, aluminum, thin films
