DOI: 10.1002/adfm.202008404

Abstract: Halide substitution in phenethylammonium spacer cations (X‐PEA+, X = F, Cl, Br) is a facile strategy to improve the performance of PEA based perovskite solar cells (PSCs). However, the power conversion efficiency (PCE) of X‐PEA… read more here.

DOI: 10.1039/d4ta00394b

Abstract: Ammonium salts are essential low-dimensional perovskite materials and are synthesized by protonation reaction, giving the amino group a positive charge. Here, 2-amino-3-methylthiazol-3-ium iodide (AMTI) and 2-amino-3-methylbenzo[d]thiazol-3-ium iodide (AMBTI) were synthesized... read more here.

DOI: 10.1039/d5cc01292a

Abstract: This study explores a conjugated spacer molecule, biphenylethylammonium bromide (bPEA), to enable efficient dimension control in quasi-two-dimensional perovskites for blue light-emitting diodes. The incorporation of bPEA improves the optoelectronic properties, thereby delivering a peak external… read more here.
