Efficient Kesterite Solar Cells via Scalable Doctor‐Blading of 2‐Methoxyethanol‐Based Molecular Ink
ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.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
Progress in Photovoltaics: Research and Applications, Volume 34, Issue 7, Page 942-956, July 2026.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.

physica status solidi (a), Volume 223, Issue 12, 24 June 2026.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.

Pressure-induced structural and electronic transitions in kesterite-type $\mathrm{Cu_{2}ZnSnS_{4}}$
, 2019 We have performed structural investigations of ordered kesterite-type Cu$_2$ZnSnS$_4$ up to 30 GPa. Our current X-ray diffraction results clearly excluded the presence of a kesterite → disordered kesterite transition reported previously between 7 and 9 ...

Phase evolution of Cu2ZnSnS4 (CZTS) kesterite thin films during the sulfurization process
, 2018 The development of high efficiency Cu2ZnSnS4 (CZTS) thin film solar cells depends on the synthesis of phase pure CZTS films. Due to the narrow phase window, it is difficult to prepare CZTS films with a pure kesterite phase (i.e., a film that lacks traces
