Physical routes for the synthesis of kesterite [PDF]

open access: yesJournal of Physics: Energy, 2019
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 ...

Recovery Mechanisms in Aged Kesterite Solar Cells [PDF]

open access: yesACS Applied Energy Materials, 2022
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.

Rapid Thermal Processing of Kesterite thin films

open access: yesCoatings, 2023
In this contribution we present work on rapid thermal annealing of as-electrodeposited thin films of Cu2ZnSnS4. The treatment was carried out in cold wall tubular reactor in dynamic conditions with variations of temperature, speed and time of the specific elements of the process.

Macroscopic versus microscopic photovoltaic response of heterojunctions based on mechanochemically prepared nanopowders of kesterite and n-type semiconductors

open access: yesSemiconductor Physics, Quantum Electronics & Optoelectronics, 2017
Mechanochemically prepared nanopowder of selenium-free kesterite Cu2ZnSnS4 (CZTS) in combination with n-type semiconductors, i.e., CdS, ZnO and TiO2, was tested in planar and bulk-heterojunction solar cells.

Band Alignments and Interfaces in Kesterite Photovoltaics [PDF]

open access: yes, 2019
The kesterite materials, Cu2ZnSn(S,Se)4, represent a promising class of absorber materials, for cheap, earth-abundant, non-toxic photovoltaic cells. However, the record efficiency of a device based on these materials is only 12.6 %, compared to 15 % required for the material to be commercially viable and 22.6 % for the related chalcopyrite material ...

Rapid Cooling After Device Annealing Suppresses Interface Losses in Cu<sub>2</sub>ZnSnS<sub>4</sub> Solar Cells Enabling High Efficiency and Stability. [PDF]

open access: yesAdv Sci (Weinh)
Rapid cooling after device annealing regulates the CdS/CZTS heterojunction and Mo/CZTS back contact, suppressing interfacial recombination and modifying the interfacial MoS2 layer, thereby enabling a 15.9% indoor PCE in pure‐sulfide CZTS solar cells.

Graphene-Engineered Rear Interfaces Enable Efficient Flexible CZTSSe Solar Cells on Metal Foils. [PDF]

open access: yesAdv Sci (Weinh)
An atomically thin graphene interlayer stabilizes the rear interface of flexible CZTSSe solar cells by regulating interfacial stress, suppressing detrimental interfacial reactions, and reducing the back‐contact barrier. This strategy simultaneously improves photovoltaic performance and mechanical durability.

Controlling the Anionic Ratio and Gradient in Kesterite Technology [PDF]

open access: yesACS Applied Materials & Interfaces, 2022
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 ...
