Issue Date: | 2018 | Publisher: | IEEE | Source: | 2018 IEEE 7TH WORLD CONFERENCE ON PHOTOVOLTAIC ENERGY CONVERSION (WCPEC) (A JOINT CONFERENCE OF 45TH IEEE PVSC, 28TH PVSEC & 34TH EU PVSEC), IEEE,p. 0160-0162 | Series/Report: | World Conference on Photovoltaic Energy Conversion WCPEC | Abstract: | The replacement dynamics of Se by S is investigated in kesterite Cu2ZnSn(S,Se)(4) and Cu2ZnGe(S,Se)(4). Two different post-sulphurization techniques yield the same results. In the initial stages of the replacement, the original selenium-rich phase coexists with a second mixed phase. This phase has an increased sulphur content of 30 %. In later stages of the reaction, the initial phase disappears in favor of the second phase. Thus, sulphur inclusions of less than 30 % seem impossible while above 30 % the sulphur amount is adjustable. | Notes: | [Neuwirth, Markus; Kalt, Heinz; Hetterich, Michael] KIT, Inst Appl Phys, D-76131 Karlsruhe, Germany.
