Abstract

The paper describes the preparation of NiOx films using Atomic Layer Deposition (ALD) and analyzes their hole transport properties. During the ALD process, NiOx films with varying properties were fabricated by adjusting the number of nickel pulses in the reaction. Various characterization techniques were employed to investigate the morphology, composition, optical, and electrical properties of the films prepared with different numbers of nickel pulses. The study reveals that as the number of Ni pulses increases, the content of Ni metal and Ni (OH)2 in the NiOx films changes, and post-annealing treatment can significantly enhance the performance of the NiOx films. Finally, NiOx was used as a hole transport layer to successfully fabricate silicon solar cells, resulting in an increase in power conversion efficiency (PCE) from 17.89% to 18.89% compared to untreated cells.

调整镍脉冲数对原子层沉积制备的氧化镍薄膜的影响

本文介绍了利用原子层沉积（ALD）技术制备氧化镍薄膜的过程，并分析了其空穴传输特性。在原子层沉积过程中，通过调整反应中镍脉冲的数量，制备出了具有不同性质的氧化镍薄膜。研究人员采用了多种表征技术来研究不同镍脉冲数制备的薄膜的形态、成分、光学和电学特性。研究表明，随着镍脉冲数的增加，镍氧化物薄膜中金属镍和镍（OH）2 的含量也会发生变化，而退火后处理可以显著提高镍氧化物薄膜的性能。最后，NiOx 被用作空穴传输层，成功制成了硅太阳能电池，与未经处理的电池相比，功率转换效率（PCE）从 17.89% 提高到 18.89%。

期刊介绍： Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
