Abstract
In this study, dielectric/metal/dielectric (DMD) transparent conductive multilayer films were fabricated with TiO₂ as the bottom layer and Ag as the middle layer, using 30 % aluminum oxide-doped zinc oxide (AZO30), aluminum-doped zinc oxide (AZO), and zinc oxide (ZnO) as the top layers, respectively. The effect of water vapor transmission rates (WVTR) of different single-layer top films on PET substrates on the stability of the photoelectric performance of the DMD multilayer films was investigated. The results showed that the AZO30 top layer exhibited the lowest WVTR, providing superior barrier properties that effectively prevented water vapor infiltration and subsequent oxidation of the metal layer, thus mitigating surface degradation. Consequently, the TiO₂/Ag/AZO30 multilayer film sustained stable photoelectric performance under high-temperature and high-humidity conditions for an extended period of 24 days. In contrast, films with AZO and ZnO as the top layer showed higher WVTR values and inferior barrier performance, leading to significant degradation of the photoelectric properties of the TiO₂/Ag/AZO and TiO₂/Ag/ZnO multilayers. These findings highlight the critical role of the top layer's barrier properties in enhancing the photoelectric stability of the DMD multilayer films. This study suggests that employing a top layer with low WVTR as part of the multilayer transparent conductive electrode can significantly improve performance stability and long-term durability.
期刊介绍:
Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties.
Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour.
Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
