Optical tunability of lead free double perovskite Cs₂AgInCl₆via composition variation

Abstract

Lead free halide double perovskites have emerged as a stable alternative to lead based hybrid perovskites. Double perovskites involving cations like In3+, Sb3+ and Bi3+ are synthesized with varing the...

Enhancement of the efficiency and thermal stability of the double perovskite Cs2AgInCl6 single crystal by Sc substitution

“…The obtained band gap is about 2.5 eV, which is smaller than that of Cs 2 AgInCl 6 in the previous report. 27,[37][38][39] Therefore, it is reasonable to deduce that the direct bandgap of Cs 2 AgInCl 6 would decrease with the doping of Sc and that is in accordance with our results as shown in Fig. 3b.…”

Facile Melting-Crystallization Synthesis of Cs2NaxAg1–xInCl6: Bi Double Perovskites for White Light-Emitting Diodes

“…The dopant concentrations of Bi 3+ are too low to be detected by XPS. The positions of the observed peaks are consistent with the expected oxidation states (Cs + , Na + , Ag + , In 3+ , and Cl – ) for the corresponding metal chlorides . The high-resolution XPS results are illustrated in Figure b–f.…”

“…The positions of the observed peaks are consistent with the expected oxidation states (Cs + , Na + , Ag + , In 3+ , and Cl − ) for the corresponding metal chlorides. 26 The highresolution XPS results are illustrated in Figure 3b−f. As for the Cs 3d spectrum, two peaks appear at 723.8 and 737.8 eV, which could be associated with Cs 3d 5/2 and Cs 3d 3/2 , respectively.…”

Polymers in High-Efficiency Solar Cells: The Latest Reports

“…The current research topic in photovoltaics is perovskite solar cells. The PSCs are cells of the latest technology, for which has been noted a very fast increase in efficiency (PCE) from 3.8% in 2009 to 25.2% in 2020, which may indicate that this type of cell will find commercial applications [ 12 , 144 , 145 ]. The perovskite solar cells are a hybrid system, a combination of organic and inorganic structures.…”

“…Research in recent years has confirmed a significant increase in the energy conversion efficiency of third-generation cells. According to the literature reports, perovskite solar cells achieve efficiencies of over 25% [ 12 ], DSSCs over 14% [ 13 , 14 ] and BHJs around 18% [ 15 ]. Furthermore, a great advantage of organic compounds is that they can be applied to various substrates using various methods.…”
