Issue Date: | 2020 | Publisher: | AMER CHEMICAL SOC | Source: | ACS APPLIED ENERGY MATERIALS, 3 (6) , p. 5120 -5125 | Abstract: | To determine if Cu(In, Ga)Se-2 (CIGS) can be submitted to the constraints that will be imposed on the solar materials of the future by an ever growing demand and necessity, we produced ultrathin (500 nm) single-stage coevaporated CIGS solar cells doped with varying amounts and types of alkali atoms. We subjected them to accelerated lifetime testing. In the present work, we observed the seeping of water into the grain boundaries which could be identified as one of the main culprits for performance degradation. In addition, this phenomenon could only be observed when alkali atoms were present in the absorber layer. | Keywords: | ultrathin solar cells;CIGS;alkali doping;materials reliability;effect of water;atom probe | Document URI: | http://hdl.handle.net/1942/31696 | ISSN: | 2574-0962 | DOI: | 10.1021/acsaem.0c00610 | ISI #: | WOS:000543715100005 | Rights: | 2020 American Chemical Society | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2021 |
