    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.
