Silicon heterojunction (SHJ) solar cells are increasingly attracting attention due to their low-temperature processing, lean steps, significant temperature coefficient, and their high bifacial capability. The high efficiency and thin wafer nature of SHJ solar cells make them ideal for use as high-efficiency solar cells. However, the complicated nature of the passivation layer and prior cleaning render a well-passivated surface difficult to achieve. In this study, developments and the classification of surface defect removal and passivation technologies are explored. Further, surface cleaning and passivation technologies of high-efficiency SHJ solar cells within the last five years are reviewed and summarized.
硅异质结（SHJ）太阳能电池因其低温工艺、步骤精简、显著的温度系数以及高双面性而越来越受到关注。SHJ太阳能电池的高效率和薄晶圆特性使其成为高效太阳能电池的理想选择。然而，钝化层的复杂性和先前的清洗使得难以实现良好的钝化表面。在本研究中，探讨了表面缺陷去除和钝化技术的发展及分类。此外，还对过去五年内高效SHJ太阳能电池的表面清洗和钝化技术进行了综述和总结。
