First Principle Investigation on Electronic Properties of Cationic and Anionic CO-Alloyed Cu2ZnSnS4 Kesterite Material [PDF]
The primary goal of kesterite alloying is to allow for fine tweaking of the material's characteristics for advanced device engineering. Additionally, it is seen as a viable solution to inherent kesterite absorber difficulties such as the Cu/Zn disorder

Recovery Mechanisms in Aged Kesterite Solar Cells [PDF]
For successful long-term deployment and operation of kesterites Cu2ZnSn(S x Se1-x )4 (CZTSSe) as light-absorber materials for photovoltaics, device stability and recovery in kesterite solar cells are investigated. A low-temperature heat treatment is applied to overcome the poor charge extraction that developed in the natural aging process.

Controlling the Anionic Ratio and Gradient in Kesterite Technology [PDF]
Accurate anionic control during the formation of chalcogenide solid solutions is fundamental for tuning the physicochemical properties of this class of materials. Compositional grading is the key aspect of band gap engineering and is especially valuable at the device interfaces for an optimum band alignment, for controlling interface defects and ...

An ITO‐Free Kesterite Solar Cell
AbstractPhotovoltaic thin film solar cells based on kesterite Cu2ZnSn(S, Se)4 (CZTSSe) have reached 13.8% sunlight‐to‐electricity conversion efficiency. However, this efficiency is still far from the Shockley‐Queisser radiative limit and is hindered by the significant deficit in open circuit voltage (VOC).

Ultrathin wide band gap kesterites
Thickness reduction of kesterite CZTS solar cells down to 250 nm is performed showing relatively small performance loss. The introduction of oxide passivation layers improves performance and a NaF treatment is used to make such back contact conductive.

Physical routes for the synthesis of kesterite
Abstract This paper provides an overview of the physical vapor technologies used to synthesize Cu2ZnSn(S,Se)4 thin films as absorber layers for photovoltaic applications. Through the years, CZT(S,Se) thin films have been fabricated using sequential stacking or co-sputtering of precursors as well as using sequential or co-evaporation of ...
