硅晶片太阳能电池仍然是领先的光伏技术，在许多地方现在提供了相当大的一部分发电。进一步采用这项技术将需要最大限度地减少设备性能损失的处理。效率损失的基本机制是光生电荷载流子在不可避免的电池表面处的复合。介电涂层已被证明可以通过不同钝化机制的组合在很大程度上防止这些损失。这篇综述的目的是提供一个概述的介电钝化涂层在过去的二十年中使用标准化的方法来衡量所有技术和材料的表面复合的指标。一个大的材料和方法的有效性进行了评估，使用这些指标和讨论的现状和前景，进一步的表面钝化的改进。(C)2017作者出版社：WILEY-VCH Verlag GmbH & Co. KGaA，魏因海姆
Silicon wafer solar cells continue to be the leading photovoltaic technology, and in many places are now providing a substantial portion of electricity generation. Further adoption of this technology will require processing that minimises losses in device performance. A fundamental mechanism for efficiency loss is the recombination of photo-generated charge carriers at the unavoidable cell surfaces. Dielectric coatings have been shown to largely prevent these losses through a combination of different passivation mechanisms. This review aims to provide an overview of the dielectric passivation coatings developed in the past two decades using a standardised methodology to characterise the metrics of surface recombination across all techniques and materials. The efficacy of a large set of materials and methods has been evaluated using such metrics and a discussion on the current state and prospects for further surface passivation improvements is provided.
