Overcoming strain‐induced vertical inhomogeneity in perovskite films for all‐perovskite tandem solar cells

open access: yesInfoMat, Volume 8, Issue 1, January 2026.
Perovskite films were found to require different‐sized passivation molecules at the top and bottom surfaces because crystal spacing varies through the film thickness. With this two‐sided passivation applied to both the high‐ and low‐bandgap layers in an all‐perovskite tandem solar cell, 27.5% efficiency was achieved.

Acidic and hydrogen peroxide treatment of polyaluminum chloride (PACL) sludge from water treatment

open access: yesWater Science and Technology, 2004
The water treatment sludge including coagulants cannot be easily removed by conventional dewatering methods. The possibility of hydrogen peroxide (H2O2) oxidation as a pretreatment to enhance the dewaterability of polyaluminum chloride (PACl) sludge from water works was investigated.
