Exploring window buffer layer technology to enhance CdTe solar cell
The short-wavelength response for traditional CdS/CdTe thin film solar cells was dramatically restricted by the CdS window layer. In order to increase short-wavelength light collection, we tried to replace CdS with Mg x Zn 1−x O (MZO). The short-wavelength quantum efficiency (QE) response was obviously increased to more than 80% at 400 nm, while fill factor

How do Buffer Layers Affect Solar Cell Performance and Solar Cell
Buffer layers are commonly used in the optimization of thin-film solar cells. For CuInSe 2-and CdTe-based solar cells, multilayer transparent conductors (TCOs, e.g., ZnO or SnO 2) are generally used in conjunction with a CdS heterojunction layer.Optimum cell performance is usually found when the TCO layer in contact with the CdS is very resistive or almost insulating.

Modeling of ZnO/MoS2/CZTS photovoltaic solar cell through window
Thought CZTS materials have become a good choice as absorbers in solar cell structures, the buffer layer optimization is still an issue for its progress. The role of the buffer layer is to provide band alignment between the CZTS and the window layer and to reduce defects and interfacial strain resulting from the window layer [7], [12].
