Title: Defect characterisation in Cu2ZnSnSe4 kesterites via resonance Raman spectroscopy and the impact on optoelectronic solar cell properties

Polycrystalline kesterite Cu2ZnSnSe4 (CZTSe) semiconductors have drawn attention as promising absorber candidates for the next generation of thin film photovoltaics. However, the narrow tolerance to stoichiometry variations that favours the formation of secondary phases and cluster defects is a challenging drawback that restrains the device performances. In this context Raman spectroscopy has demonstrated to be a powerful tool for the characterization of CZTSe, allowing the assessment of the relevant parameters such as structure, crystal quality and secondary phases.
