中文摘要

摘要 全球向可持续能源的转型使光伏(PV)技术,特别是晶体硅(c-Si)太阳能电池,占据了约97%的光伏市场,这一发展由降低成本和提高效率的双重需求所驱动。本文对实现上述目标的关键步骤——c-Si硅片表面纹理化技术——进行了深入评述。我们首先探讨了从传统的游离磨料浆料切割(LASS)向金刚石线锯切割(DWS)的转变,后者具有更高的生产效率、更少的切口损耗,并能够实现更薄硅片的制造。随后,本文深入分析了多种纹理化方法,包括气相腐蚀、反应离子刻蚀(RIE)、激光刻蚀、酸性刻蚀、碱性刻蚀以及金属辅助化学刻蚀(MACE),系统评估了这些方法在硅表面构建最优光捕获结构的有效性。我们的综合分析表明,尽管传统的湿法刻蚀技术仍占主导地位,但MACE和RIE等新兴方法在下一代高效太阳能电池中展现出显著潜力。其中,通过MACE实现的倒金字塔结构在优化光吸收和提升电池性能方面表现突出,成为最具前景的技术路径之一。本综述提供了当前硅片纹理化技术的前沿进展概述,并对未来c-Si太阳能电池的发展方向提出了深刻见解,为实现高效率、低成本的光伏器件奠定了基础。

English Abstract

Abstract The global transition towards sustainable energy has positioned photovoltaic (PV) technology, particularly crystalline silicon (c-Si) solar cells, dominating approximately 97 % of the overall PV market, driven by dual imperatives: cost reduction and efficiency enhancement. This review paper critically analyzes cutting-edge texturing technologies for c-Si wafers, a crucial step in achieving these objectives. We begin by examining the shift from conventional loose abrasive slurry sawing (LASS) to diamond wire sawing (DWS), which offers superior productivity, reduced kerf loss, and enables the production of thinner wafers. The paper then delves into various texturing methods, including vapor etching, reactive ion etching (RIE), laser etching, acid etching, alkali etching, and metal-assisted chemical etching (MACE), evaluating their efficacy in creating optimal light-trapping structures on silicon surfaces. Our comprehensive analysis reveals that while traditional wet etching methods remain prevalent, novel approaches such as MACE and RIE show particular promise for future high-efficiency solar cells. The inverted pyramid structure, achievable through MACE, emerges as a leading contender for optimizing light capture and cell performance. This review provides a state-of-the-art overview of texturing technologies and insights into the future of c-Si solar cells, paving the way for high-efficiency, cost-effective photovoltaic devices.
