Zn(O,S) Buffer Layer for in Situ Hydrothermal SbS Planar Solar Cells.

Hydrothermal deposition is emerging as a highly potential route for antimony-based solar cells, in which the Sb(S,Se) is typically in situ grown on a common toxic CdS buffer layer. The narrow band gap of CdS causes a considerable absorption in the short-wavelength region and then lowers the current density of the device. Herein, TiO is first evaluated as an alternative Cd-free buffer layer for hydrothermally derived SbS solar cells.
