Fast quantum efficiency measurement of solar cells by Fourier transform photocurrent spectroscopy

Spectral response of amorphous–nano-crystalline silicon thin films

“…The quantum efficiency was measured by using FTIR spectrometer equipped for the near infrared and visible region and an improved FTPS set-up [14].…”

Optical absorption spectra of Cu2ZnSn(S,Se)4 thin-film solar cells by Fourier transform photocurrent spectroscopy

“…There are methods that have been used to measure optical absorption, such as ellipsometry 18) and photothermal deflection spectroscopy (PDS). 19) Fourier transform photocurrent spectroscopy (FTPS), [20][21][22] which is based on the constant photocurrent method (CPM), 23) is an optical absorption measurement method. In FTPS, optical absorption coefficient is obtained from photocurrent.…”

Comparison of photocurrent spectra measured by FTPS and CPM for amorphous silicon layers and solar cells

“…Recently we have introduced a fast and highly sensitive method for the evaluation of the optical absorption coefficient of photoconductive thin films such as microcrystalline silicon layers [1] and later also for the quality assessment of thin film silicon solar cells [2]. High accuracy and reproducibility of this method, Fourier Transform Photocurrent Spectroscopy (FTPS), has also been demonstrated by interpreting the measured FTPS spectra of solar cells (single or tandem) as external quantum efficiency data [3,4].…”
