Stability of Cu2ZnSnSe4/CdS heterojunction based solar cells under soft post-deposition thermal treatments

Photoelectrochemical Properties and Characterization of CdS/CdSe Heterojunctions Obtained by CBD on ITO and p–Si Substrates

“…The Raman spectra of the CdS/CdSe films grown on both ITO and Si substrates are presented in Figure 6 within the Raman shift range 200 cm −1 to 700 cm −1 . The spectra show a peak at 299 cm −1 , attributed to the longitudinal optical (LO) phonon mode of CdS [37–40] . The broadening of the peak is attributed to the polycrystalline structure [41,42] and the shouldering of the CdSe.…”

“…The spectra show a peak at 299 cm À 1 , attributed to the longitudinal optical (LO) phonon mode of CdS. [37][38][39][40] The broadening of the peak is attributed to the polycrystalline structure [41,42] and the shouldering of the CdSe. Three different peaks are observed in the Raman shift spectrum of CdS/CdSe on the Si substrate.…”

To grind or not to grind? The influence of mechanical and thermal treatments on the Cu/Zn disorder in Cu2ZnSn(SxSe1-x)4 monograins

“…In this regard, the development of a methodology enabling an estimation of the Cu/Zn disorder level, that is based on a simple, easily accessible analytical technique that does not require any specific sample preparation and can be applied both for powder and thin film samples is of the outmost important for the whole scientific community. Previously, analysis of the Raman spectra of CZTS and CZTSe compounds allowed to develop a methodology for the assessment of the order parameter using changes in different features of the Raman spectra [9,30]. A more detailed analysis of the Raman spectra of the as-grown and treated CZTSSe monograins shows clearly a significant difference in the full width at half maximum (FWHM) of the Raman peaks in the as-grown, "disordered" and "ordered" CZTSSe (Figure 3).…”
