“…Trans parent conductive electrode material is probably the most expen sive part of the ECO. Indium Tin Oxide (ITO) and Aluminum doped Zinc Oxide (AZO) (13], due to their two main opta electrical prop erties (electrical conductivity and optical transparency), as well as their ability to be deposited as thin films. Generally, the balance of the optimal optical and electrical properties is difficult to realize because these two properties are usually mutually exdusive, and the overall conductivity of the wide band gap oxide semi conducting material is somehow limited.…”

The "Oielectric/Metal/Oielectric" (OMO) stacked films being used as transparent and conductive (TC) electrodes, have demonstrated excellent application in the ElectroChromic (EC) process and devices. In this work, multilayers (IAI) made of 50 nm of Indium Tin Oxide (IT0)/5 nm of metallic sil ver (Ag)/30 nm of ITO that exhibit band gap, low resistance of 7.4 Q and the high figure of merit of 9.9 x 10 3 Q 1 were introduced in a complete five layer Glass/IAI/NiOx/LlCIO4 PC PMMA/WO3/IAI/Glass ElectroChromic De vice (ECO). The single IAI electrode as well as the two actives EC layers Glass/IAI/Niûx and Glass/IAI{WO 3 were firstly characterized for their TC and EC properties respectively. Then, the EC properties of the complete five layer ECO were analyzed. Fast response time (2.02 s for the bleaching and 225 s for complete coloration), wide optical modulation in the visible light region (-55% at 550 nm), long lifetime (more than 6000 s), large capacity and good stability as well as high coloration efficiency (31.7 cm 2 C 1) were obtained The improved EC performance of ECO were related to the good electrical and optical properties of IAI electrode.

“…Later in the simulation when doping concentrations have been optimized (As shown in Table 4) it is seen that, in all the cases AZO's performance is better than ITO layer. It may be due to the reason that, AZO layer has better optical transparency and thermal stability [52]. Nevertheless, the debate between the values of AZO vs. ITO for thin lm solar cell is still ongoing [53].…”

Solar cells made of Cadmium telluride (CdTe), copper indium gallium selenide (CIGS) and copper zinc tin sulfide (CZTS) are currently the most widely studied thin film technologies.To increase the performance and for better understanding of the behavior of CdTe, CIGS and CZTS solar cell simulations have been performed using WxAMPS software. Moreover, all the solar cells have been simulated with different buffer layers and transparent conductive oxide (TCO) layers such as Cadmium Sulphide (CdS), Zinc Sulphide (ZnS), Aluminum Zinc Oxide (AZO) and Indium Tin Oxide (ITO).Variations in the thickness and doping concentrations of TCO layers, buffer layers, and absorber layers have been done to test the performance of the solar cells.The effects of using a Back-Surface Reflector (BSR) layer made of Zinc Telluride (ZnTe) have also been studied.Furthermore, the simulation work is exceptional in this regard since all of the layers of CdTe, CIGS, and CZTS solar cells were modeled using optical parameters (absorption coefficients) from the literature. All the solar cell's open circuit voltage (Voc), short circuit current (Isc), maximum power (Pm), fill factor (FF), and photovoltaic efficiencies have been represented in this work. The simulation results may provide valuable insight in developing and better understanding of high-efficiency thin film solar cells.

“…The device junction in most heterojunction solar cells is created between TCO and Si or metal and Si. [2] TCOs that are commonly utilized are all n-type doped. Indeed, one of the major problems in the research is to create fresh p-type TCOs with comparable performance to their n-type counterparts.…”

Copper oxide/nickel oxide (CuO/NiO) thin films were deposited on glass substrates by the Physical vapor deposition (PVD) Technique and then annealed at different temperatures of 280°C, 320°C, and 360°C for 2 hours. The effects of the annealing temperature on the optical and structural properties of the CuO/NiO thin films were studied. X-ray diffraction suggests that a Monoclinic and cubic structure with a strong (1 1 1) and (2 2 0) for each of CuO and NiO respectively preferred orientation which remained the same with different heat treatments. And the crystallite size increases with annealing temperature, and the lattice constants of CuO/NiO thin films were also obtained from XRD data. Also, it is found that with the increase of different heat treatments, the optical absorption spectra showed that with increasing annealing temperatures, the absorption coefficient decreases, and the edge absorption shifts to longer wavelengths. The direct optical band gap decreases from 2.88 eV, 2.84ev to 2.74 eV for as-deposited and annealed CuO/NiO thin film at 280 °C, 320 °C, and 360 °C respectively.
