Evaluation of optical absorption in CZTSSe within cell structure was tried by Fourier Transform Photocurrent Spectroscopy (FTPS) method. Based on optical band gap energy, E_o and Urbach energy, E_u results obtained from this method, evaluation of optical absorption in CZTSSe within cell structure is possible by FTPS method.
