The impact of precursor thickness and surface roughness on the power factor of Cu2ZnSnS4 (CZTS) at near room temperature: Spin-coating deposition

Spin-coated CZTS films prepared by two different precursor mixing regimes, at room temperature and at 150 °C

“…at room temperature, Zakaria et al 20 min at [ 2 ], Tanaka et al at for 1 h [ 6 ], Hosseinpour at al. at for 30 min [ 15 ], Laghafour at for 1 h [ 16 ], Ahmoum et al at for 2 h [ 17 , 18 ], etc. However, to the best of our knowledge, there are no reports on films prepared from precursors being mixed at higher temperatures than 90 °C, using different mixing protocols, which may have an impact on the properties of the CZTS films.…”
