Ag‐Induced Phase and Defect Engineering of Co‐Evaporated Sb2Se3 Thin Films for Enhanced Photovoltaic Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The sequential formation of Ag2Se and AgSbSe2 phases at the Sb2Se3/Mo interface upon Ag incorporation in co‐evaporated Sb2Se3 solar cells promotes grain growth and defect passivation. These newly formed intermediate phases enhance crystallinity and suppress recombination, leading to significant improvements in open‐circuit voltage, fill factor, and ...

Ag‐Promoted Na Retention for Synergistic Defect Passivation in Kesterite Solar Cells

Advanced Energy and Sustainability Research, Volume 7, Issue 7, July 2026.
A synergistic Ag–Na codoping strategy in solution‐processed kesterite solar cells enables simultaneous lattice ordering and defect passivation. Ag promotes grain growth and Na retention, while Na enhances carrier concentration and reduces recombination.

S/Ge dual gradient spontaneous construction for improved CZTSSe solar cells

Nano Research
A key reason for Cu2ZnSn(S,Se)4 (CZTSSe, 15.8%) solar cells lagging far behind Cu(In,Ga)Se2 (CIGS, 23.6%) in efficiency is its inability to autonomously form a dual-gradient bandgap via Ga gradient, critical for the simultaneous efficient light ...
