Engineering the counteranions of ethylenediammonium, a useful passivation molecule for perovskites, improves its solubility and clarifies how power conversion efficiency depends on concentration as well as on the choice of counteranion. This approach leads to improved reproducibility in perovskite solar cells.

Synthesis and Nucleophilic Reactions of Bifunctional Thiourea S,S,S-Trioxides [PDF]
The synthesis of bifunctional thioureas and the corresponding thiourea S,S,S-trioxides has been examined. Two methods for the synthesis of the bisthioureas were employed. One involved the treatment of a diamine with silicon tetraisothiocyanate in benzene.

Tin‐based perovskites offer a lead‐free alternative for perovskite light‐emitting diodes (PeLEDs) but suffer from poor performance due to uncontrolled crystallization and Sn(II) oxidation. Here, NH4SCN is introduced into a DMSO‐free precursor to regulate crystallization, suppress Sn(II) oxidation, and reduce defects, enabling pure‐red PeLEDs with an ...
