Zn2+ and Cu2+ doping of one-dimensional lead-free hybrid perovskite ABX3 for white light emission and green solar cell applications

Structural and Optical Characterization of a New Tetra- and Hexa-Coordinated Cd-Based Hybrid Compound with White Light Emission

“…Similarly to the known Cd-based organic inorganic hybrid materials [18,28,29,34,41], the absorption spectrum presented in Figure 4 shows an intense band in the UV region…”

“…Up to now, achieving white light emission has been recognized as a critical step for solid-state lighting to become a more efficient lighting source than conventional ones [19][20][21][22][23]. Very recently, low-dimensional Cd-based organic-inorganic semiconductors, with tetrahedral or octahedral coordination around the Cd cations, proved their fascinating luminescent properties as solid state white light emitters [24][25][26][27][28][29][30][31]. Scrutiny of the luminescence response of the previously studied Cd-based hybrid materials revealed that their emission behavior is very similar to that observed for pure CdX 2 (X = Cl, Br and I) [32][33][34].…”

Exploring the Crystal Structure, Thermodynamics, and Molecular Dynamics of NH(CH3)3CuCl3·2H2O Organic–Inorganic Hybrid Perovskite

“…Numerous studies on organic–inorganic hybrid ABX 3 compounds have yielded meaningful results owing to their broad applicability. In recent efforts to develop advanced materials, researchers have focused on developing materials with ABX 3 stoichiometry, where A represents the organic cation (A = NH 3 CH 3 , NH 2 (CH 3 ) 2 , NH­(CH 3 ) 3 , and N­(CH 3 ) 4 ), B denotes the metal cation (B = Co, Zn, Cu, Mn, and Cd), and X denotes the halide anion (X = Cl, Br, and I) for highly efficient photovoltaic applications at a low cost. ,− Crystals with general formulas ABCl 3 ·2H 2 O and ABCl 3 have garnered considerable attention in recent years due to their specific magnetic properties at low temperatures. Most of these materials undergo multiple structural phase transitions, often related to the reorientation dynamics of the substituted ammonium group.…”

Investigation on the organic–inorganic hybrid crystal [NH2(CH3)2]2CuBr4: structure, phase transition, thermal property, structural geometry, and dynamics

“…However, CH 3 NH 3 Pb X 3 -based photovoltaics demonstrate high instability under typical environmental conditions, notably moisture, as well as high toxicity owing to the bioaccumulation of Pb 13 – 18 . Thus, researchers have suggested the substitution of Pb with other low-toxicity or eco-friendly metals such as Cu and Zn to develop Pb-free photovoltaic devices 19 . The urgent need to develop eco-friendly hybrid perovskite solar cells has recently been highlighted.…”
