摘要

介绍了Al2O3的材料性质及其原子层沉积制备方法, 详细阐述了该材料的钝化机制(化学钝化和场效应钝化), 并从薄膜厚度、热稳定性及叠层钝化等角度阐释其优化方案. 概述了Al2O3钝化在晶体硅太阳电池中的应用, 主要包括钝化发射极及背面局部扩散电池和钝化发射极及背表面电池. 最后, 对Al2O3钝化工艺的未来研究方向和大规模的工业应用进行了展望.

关键词:

The material characteristics and one of the preparation methods, atomic layer deposition of Al2O3 are introduced. The passivation mechanisms (chemical passivation and field-effect passivation) of Al2O3 films are demonstrated comprehensively, and optimization methods from the angles of film thickness, thermal stability and stack passivation are illuminated. The application of Al2O3 passivation in the crystalline silicon solar cell is provided, including passivated emitter rear locally diffused cell and passivated emitter and rear cell. Finally, the future study of the Al2O3 passivation process and the application to industry production are proposed.
