Solar RRL, Volume 10, Issue 6, 29 March 2026.This study investigates the effect of the chemical composition on the properties of A(BB’)(XX’)3$_3$ inorganic halide perovskites with density functional theory. By correlating distortion amplitudes with both composition and the Goldschmidt tolerance factor, we propose a pragmatic approach to designing more stable and efficient perovskites, advancing ...

Solar RRL, Volume 10, Issue 6, 29 March 2026.In2O3:Ti is identified as a thermally stable and highly near‐infrared transparent back contact for (Ag,Cu)(In,Ga)Se2 solar cells and modules. Under rear illumination, the short‐circuit current density is improved by ≈ 3 mA/cm2 as compared with a more standard In2O3:Sn back electrode.

International Journal of Mining Science and TechnologyA novel small molecule depressant (M-DEP) was used to separate chalcopyrite and molybdenite via flotation. The results showed that M-DEP had an excellent selective depression on molybdenite, while had little effect on the flotation of chalcopyrite.

Band Structure Engineering of Multinary Chalcogenide Topological Insulators
, 2011 Topological insulators (TIs) have been found in strained binary HgTe and ternary I-III-VI2 chalcopyrite compounds such as CuTlSe2 which have inverted band structures. However, the non-trivial band gaps of these existing binary and ternary TIs are limited

Leaching of a Mongolian chalcopyrite concentrate
Mongolian Journal of Chemistry, 2018 A Mongolian chalcopyrite flotation concentrate was leached using sodium hypochlorite adjusted to different pH using hydrochloric acid. It was found that using a starting pH of below 5.0 resulted in more efficient leaching.
