银合金化和KF后处理是提高CIGS太阳能电池效率的两种方法。尽管在文献中已经表明，KF对于减少的KF量改善了ACIGS器件性能，但是在目前对较低带隙ACIGS的研究中，KF对Voc是有害的。在ACIS+KF膜中，J-V曲线也表现出明暗交叉。这激发了在具有和不具有KF的低带隙（A）CIS膜上生长CdS的研究。SEM和GDOES表明在Ag合金CIS上CdS的生长是不同的。
Silver alloying and KF post-deposition treatments are 2 approaches to increase the efficiency of CIGS solar cells. Although it has been shown in the literature that KF improves ACIGS device performance for reduced KF amounts, in present studies of lower bandgap ACIGS, KF is detrimental on Voc. J-V curves also exhibit light-to-dark crossover in ACIS+KF films. This has motivated a study on the growth of CdS on low bandgap (A)CIS films with and without KF. SEM and GDOES suggest a different CdS growth on Ag alloyed CIS.
