Buried Interface Engineering via a Bifunctional Guanidino‐Carboxyl Molecular Bridge for Enhanced Performance and Stability in Perovskite Solar Cells

EcoEnergy, EarlyView.
A bifunctional molecular bridge using 4‐guanidinobutanoic acid (GCC) is constructed to comprehensively tailor the buried interface of PSCs. By passivating oxygen vacancies, optimizing energy‐level matching, and regulating perovskite crystallization, this strategy simultaneously boosts the power conversion efficiency to 25.37% (20.01% for 13.4 cm2) and ...

Leaching Efficacy of Ethylenediaminetetraacetic Acid (EDTA) to Extract Rare-Earth Elements from Monazite Concentrate

Crystals
Alkaline EDTA solution has been previously identified as an effective leaching agent for solubilising rare-earth oxalates. These oxalates are the product of an oxalic acid conversion leach dissolving monazite and redepositing the salt.
