Raman spectroscopy study on in-situ monitoring of Cu2ZnSnS4 synthesis

• This study investigates the possibility of Raman spectroscopy as an in-situ monitoring tool for the synthesis of the solar cell material Cu2ZnSnS4 (CZTS) by annealing a stacked precursor ZnS/Cu2SnS3 on a Mo-coated glass substrate. Temperature dependent behaviour of Raman scattering for ZnS and Cu2SnS3 is studied. Both phases can still be detected at respectively 450 degrees C and 550 degrees C. Annealing of Mo/CTS/ZnS precursor stacks resulted in in-situ observation of kesterite CZTS formation with Raman spectroscopy. This is a step towards in-situ optical process control desired in kesterite fabrication.
