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

Semiconductor 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.

Recovery Mechanisms in Aged Kesterite Solar Cells [PDF]

ACS 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.

Evolution of the Cu2ZnSnS4 phase based on the sulfurization-crystallisation duration of the CuS/SnS/ZnS stack formed by thermal evaporation

Journal of Asian Ceramic Societies, 2023
Binary sulfides were deposited by sequential thermal evaporation with the stacking order glass/CuS/SnS/ZnS and subsequently subjected to a sulfurization-crystallization process, considering two thermal treatment time intervals, 5 and 20 min.

An ITO‐Free Kesterite Solar Cell

Small, 2023
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).

Molecular Cluster-Controlled Quasi-Epitaxial CZTSSe/CdS Heterojunction Enables 12.3% Efficiency of Flexible Solar Cells. [PDF]

Adv Sci (Weinh)
By controlling the synthesis of CdS molecular clusters, a quasi‐epitaxial heterojunction is directly constructed during chemical bath deposition, enabling flexible kesterite solar cells to achieve an efficiency of 12.3%. Abstract Flexible Cu2ZnSn(S,Se)4 (CZTSSe) solar cells have garnered significant attention in photovoltaics.

Ultrathin wide band gap kesterites

Faraday Discussions, 2022
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

Journal 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 ...

Calculation for High Pressure Behaviour of Potential Solar Cell Materials Cu₂FeSnS₄ and Cu₂MnSnS₄

Crystals, 2021
Exploring alternatives to the Cu2ZnSnS4 kesterite solar cell absorber, we have calculated first principle enthalpies of different plausible structural models (kesterite, stannite, P4¯ and GeSb type) for Cu2FeSnS4 and Cu2MnSnS4 to identify low and high ...
