Abstract

Zinc oxide (ZnO) is an important electron transfer layer (ETL) material due to its optical and electrical properties, maintaining its pivotal role in advancing perovskite solar cells (PSCs) given its high experimental accessibility and reported high power conversion efficiencies (PCEs). Recent studies reveal that doping ZnO nanomaterials with dual-functioning rare-earth metal (REM) ions can further bolster PCEs of ZnO-based PSCs. This review synthesizes recent empirical studies on REM-doped ZnO, focusing on enhancing PSC electron mobility, stability, and mitigating photocarrier recombination. Additionally, it examines the shift from mesoscopic to planar PSC architectures, underscores synthesis/fabrication strategies, and investigates REMs’ potential in ZnO for up/down conversion processes. Despite potential cost implications, REMs consistently achieve remarkable PCEs of up to 22.9% in ZnO-based devices.

稀土金属掺杂氧化锌增强钙钛矿太阳能电池：电子迁移率、稳定性和光载流子复合的研究进展

氧化锌（ZnO）是一种重要的电子转移层（ETL）材料，由于其高实验可及性和高功率转换效率（pce），在钙钛矿太阳能电池（PSCs）的发展中保持着关键作用。近年来的研究表明，在ZnO纳米材料中掺杂双功能稀土金属（REM）离子可以进一步增强ZnO基psc的pce。本文综述了近年来稀土掺杂ZnO的经验研究，重点是提高PSC电子的迁移率、稳定性和减轻光载流子重组。此外，它还研究了从介观结构到平面PSC结构的转变，强调了合成/制造策略，并研究了REMs在ZnO中的上/下转换过程的潜力。尽管存在潜在的成本影响，但在基于zno的器件中，REMs始终能够实现高达22.9%的显着pce。

期刊介绍： The International Journal of Energy Research (IJER) is dedicated to providing a multidisciplinary, unique platform for researchers, scientists, engineers, technology developers, planners, and policy makers to present their research results and findings in a compelling manner on novel energy systems and applications. IJER covers the entire spectrum of energy from production to conversion, conservation, management, systems, technologies, etc. We encourage papers submissions aiming at better efficiency, cost improvements, more effective resource use, improved design and analysis, reduced environmental impact, and hence leading to better sustainability. IJER is concerned with the development and exploitation of both advanced traditional and new energy sources, systems, technologies and applications. Interdisciplinary subjects in the area of novel energy systems and applications are also encouraged. High-quality research papers are solicited in, but are not limited to, the following areas with innovative and novel contents: -Biofuels and alternatives -Carbon capturing and storage technologies -Clean coal technologies -Energy conversion, conservation and management -Energy storage -Energy systems -Hybrid/combined/integrated energy systems for multi-generation -Hydrogen energy and fuel cells -Hydrogen production technologies -Micro- and nano-energy systems and technologies -Nuclear energy -Renewable energies (e.g. geothermal, solar, wind, hydro, tidal, wave, biomass) -Smart energy system
