Issue Date: | 2021 | Publisher: | IEEE | Source: | IEEE, p. 1179 -1181 | Abstract: | In modern Cu(In,Ga)Se2 (CIGS) solar cell production, alkali-poor substrates are becoming increasingly common. Thus, understanding the effect of alkali atoms on the growth of the CIGS absorber has become crucial. We studied this impact by comparing the bias dependent admittance spectroscopy response of CIGS solar cells grown with varying amounts of sodium using two different growth processes. The absence of sodium led to an intense response which is progressively replaced by other response domains as the sodium supply increases. We linked these new domains to Na accumulation and a resulting increase in band bending at the CIGS/CdS interface. | Notes: | Kohl, T (corresponding author), Hasselt Univ Partner Solliance, Inst Mat Res IMO, Wetenschapspk 1, B-3590 Diepenbeek, Belgium.; Kohl, T (corresponding author), Imec Div IMOMEC Partner Solliance, Wetenschapspk 1, B-3590 Diepenbeek, Belgium.; Kohl, T (corresponding author), EnergyVille, Thorpk,Poort Genk 8310 & 8320,3600, Genk, Belgium. | Keywords: | admittance spectroscopy; thin film photovoltaics; CIGS; loss map; alkali;doping | Document URI: | http://hdl.handle.net/1942/35914 | ISBN: | 978-1-6654-1922-2 | DOI: | 10.1109/PVSC43889.2021.9518612 | ISI #: | WOS:000701690400271 | Category: | C1 | Type: | Proceedings Paper | Validations: | ecoom 2022 |
