Band Gap Tuning of Cu2ZnGeSxSe4-x Absorbers for Thin-Film Solar Cells
In this work, kesterite-type Cu2ZnGeSxSe4-x absorbers were prepared by a two-step process for use in thin-film solar cells. Their high band gap makes them an interesting candidate as top cells in multijunction solar cells. However, an exact tuning of the

Electronics of Anion Hot Injection-Synthesized Te-Functionalized Kesterite Nanomaterial
Metal chalcogenides such as copper zinc tin sulfide (CZTS) have been intensively studied as potential photovoltaic cell materials, but their viability have been marred by crystal defects and low open circuit potential (Voc) deficit, which affected their ...

Efficient Kesterite Solar Cells via Scalable Doctor‐Blading of 2‐Methoxyethanol‐Based Molecular Ink
A new record efficiency of 13.26% has been achieved for doctor‐bladed CZTSSe solar cells, fabricated for the first time from an MOE‐based molecular ink in ambient air. Cu2ZnSn(S,Se)4 (CZTSSe) thin‐film solar cells have garnered significant interest owing to their appealing properties, such as earth‐abundant composition, environmental friendliness, high

Silver‐Alloyed Wide‐Bandgap (Ag,Cu)(In,Ga)S2 Thin‐Film Solar Cells With 15.5% Efficiency
This study reports improvements in compositional homogeneity, microstructure, enhanced radiative recombination, and extended carrier lifetime of CIGS absorber via Ag incorporation. The optimal Ag‐alloyed CIGS solar cells achieve 15.5% PCE and 948 mV VOC, competing with the VOC of the Ag‐free reference sample from the same batch.

This study investigates the effects of vanadium ion implantation on pristine copper zinc tin sulphide (CZTS) thin films. The CZTS thin films were synthesized via a two‐stage process: electron beam deposition of metal precursors (Cu, Zn, and Sn) followed by sulphurization in a tube furnace at 500°C for 30 min.

Partial and Total Substitution of Zn by Mg in the Cu2ZnSnS4 Structure
Cu 2 ZnSnS 4 (CZTS) is a quaternary semiconductor that has emerged as a promising component in solar absorber materials due to its excellent optical properties such as band-gap energy of ca. 1.5 eV and significant absorption coefficient in

A Comparative Numerical Modeling of High‐Efficient CBTS Solar Cell Using SCAPS‐1D
The highest efficiency achieved is 18.42%, 21.51%, and 21.6% for optimized CBTS/CdS/FTO, CBTS/SnS2/FTO, and CBTS/Cd0.1Zn0.9S/FTO solar cell, respectively. The results prove that low‐toxic Cd0.1Zn0.9S buffer layer provides best performance among all three buffer layers and SnS2 buffer layer also shows promising results.
