硅异质结电池的光浸泡益处向模块的可转移性
Transferability of the light-soaking benefits on silicon heterojunction cells to modules
摘要：
我们研究了光浸泡和正向偏压处理对SHJ太阳能电池和组件的影响，特别是层压过程中发生的热处理的影响。一个显着的性能增加后观察到的电偏置或光浸泡，这被证明是潜在的部分复位的层压过程。这种复位通过使具有相同热预算的单元退火来再现。层压后的第二次处理再次改善了性能，并且独立于层压前处理达到了类似的最终性能。因此，层压后的单次处理能够实现最大的模块输出，而无需从电池预处理中获得任何益处。尽管电池对正向偏压的反应总体上更好，但模块对光浸泡的反应略好。
英文摘要：
We investigate the effect of light soaking and forward electric bias treatment on SHJ solar cells and modules, and in particular the influence of the thermal treatment occurring during lamination. A substantial performance increase is observed after electric bias or light soaking, which is shown to be potentially partly reset by the lamination process. This reset is reproduced by annealing the cells with the same thermal budget. A second treatment after lamination again improves performances, and a similar final performance is reached independently of the pre-lamination treatment. Therefore, a single treatment after lamination enables maximal module output without any benefit from a cell pre-treatment. Whereas cells react overall better to forward bias, modules show a slightly better response to light soaking.
