Abstract
A transparent device in perovskite HEO La(Mn0.2Cr0.2Fe0.2Co0.2Ni0.2)O3 modified Cu2Y2O5/CdIn2O4 is prepared via a simple approach of sol-gel method. The Cu2Y2O5/La(Mn0.2Cr0.2Fe0.2Co0.2Ni0.2)O3/CdIn2O4 exhibits high transparency of ∼85–90 %, obvious photovoltaic conversion efficiency enhancement of ∼2.5 × 103-folds (PCE of ∼1.12 %), and stable output in 5-months. This is mainly attributed to the La(Mn0.2Cr0.2Fe0.2Co0.2Ni0.2)O3 modification, as well as the appropriate Fermi level and high quantum yield. In this system, the La(Mn0.2Cr0.2Fe0.2Co0.2Ni0.2)O3 solid solution, with extra carrier injecting/driving from synergism of mixed transition metals charge compensation and lattice distortion, can improve the carrier kinetic equilibrium for PCE-transparency balance. Additionally, it can increase p-type conductivity through the synergism of Cu vacancy/interstitial oxygen. Moreover, the inorganic perovskite HEO La(Mn0.2Cr0.2Fe0.2Co0.2Ni0.2)O3 with modification stability is beneficial for the actual applications.
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.
