Impact of Lithium as Interfacial Treatment for CZTSSe Solar Cells

2024 IEEE 52nd Photovoltaic Specialist Conference (PVSC)
Cu2ZnSn(S,Se)4 (CZTSSe), despite its slow progress in terms of efficiency, stands out as a viable option for solar cell absorber materials due to its comparatively low-cost fabrication process, and abundance of constituent elements. The efficiency of CZTSSe faces challenges, particularly a notable Voc deficit arising from its non-stoichiometric nature ...

Device Postannealing with Superficially Ag-Modified Absorber for High-Efficiency Cd-Free Cu₂ZnSnS₄ Solar Cells. [PDF]

Small Sci
A superficial Ag‐modification process using spin‐coated Ag2ZnSnS4 layer on presulfurized CZTS precursor is proposed to improve the surface defect properties. The absorber fabrication process reduces the interfacial nonradiative recombination loss and suppresses the generation of deep defects during device annealing, enabling 10.53% efficient Cd‐free ...

Linearly arranged polytypic CZTSSe nanocrystals [PDF]

Scientific Reports, 2012
Even colloidal polytypic nanostructures show promising future in band-gap tuning and alignment, researches on them have been much less reported than the standard nano-heterostructures because of the difficulties involved in synthesis. Up to now, controlled synthesis of colloidal polytypic nanocrsytals has been only realized in II-VI tetrapod and ...

Theoretical analysis of CZTS/CZTSSe tandem solar cells. [PDF]

Optical and Quantum Electronics, 2021
Abstract Kesterite CZTSxSe1−x has a band gap range from 1 to 1.5eV depending upon S/Se ration. The tandem of kieserite solar cell is proposed and simulated in SCAPS-1D for device configuration and analysis of the performance. CZTS of bandgap 1.5eV as top cell and CZTSSe of bandgap 1.1eV as bottom cell are stacked in tandem for the structure ...

Using Cu–Zn–Sn–O Precursor to Optimize CZTSSe Thin Films Fabricated by Se Doping With CZTS Thin Films

Frontiers in Chemistry, 2021
The copper–zinc–tin oxide (CZTO) precursor was synthesized to avoid sudden volume expansion from CZTO precursor to Cu2ZnSnS4 (CZTS) thin films and smooth CZTSSe thin-film surfaces without pinholes.

Performance improvement of Cu2ZnSn(S,Se)4 thin-film solar cells by optimizing the selenization temperature

AIP Advances, 2021
In this work, Cu2ZnSnS4 (CZTS) precursor films were deposited using a water-based solution approach. Subsequently, selenization was performed at different temperatures in the range of 480–610 °C to prepare Cu2ZnSn(S,Se)4 (CZTSSe) absorber-layer films ...
