We further assessed the effect of absence of inversion symmetry on the photocurrent In conclusion, we determined the athermal ground-state structure of Sn 2 SbS 2 I 3 to be the P 2 1 /c spacegroup. We find significant cation disordering between 300 K and 900 K, and confirm the predicted disordered Cmcm room temperature structure using X-ray diffraction.
