Double perovskite oxides La2NiMnO6 and La2Ni0.8Fe0.2MnO6 for inorganic perovskite solar cells

Abstract

Nanopowders of La 2 Ni 0.8 Fe 0.2 MnO 6 and La 2 NiMnO 6 double perovskite oxides were synthesized by glycine-nitrate combustion method. The obtained materials were characterized using X-ray diffraction, scanning electron microscopy and optical measurements. Thin nanostructured layers based on the prepared materials were used as light absorbing layers for fabrication of inorganic perovskite solar cells (PSCs). Electron transport layers for the PSCs were prepared using TiO 2 and ZrO 2 nanostructured layers. The best performance of 3.7 % under AM1.5G illumination was obtained for the PSC structure glass/FTO

Planar perovskite solar cells with La2NiMnO6 buffer layer

“…LNMO-based buffer layers were deposited on the FTO-glass substrates following the same spin coating and annealing protocols using the 5-fold diluted stock solution and were used further for PSCs fabrication. FTO glass substrates coated by cTiO 2 layer were obtained following the technique described in [17].…”

Efficiency Improvement of Lead‐Free La2NiMnO6‐Based Double Perovskite Solar Cells Using Numerical Simulation

“…[12] For example, Kozlov et al obtained a PCE of 3.7% using glass/FTO/ZrO 2 /La 2 Ni 0.8 Fe 0.2 MnO 6 / Spiro-OMeTAD/Au configuration (where FTO and Spiro-OMeTAD are flourine doped tin oxide and subderivative of orgainc 2,2 0 ,7,7 0 -tetrakis (N,N-di-p-methoyphenyl-amine)9,9 0spirobifluorene). [13] Nikolskaia et al improve the photosensitivity by up to 7% for inorganic La 2 NiMnO 6 by incorporating Fe 3þ ions. [14] Kumar et al optimized the PCE of FTO/TiO 2 / La 2 NiMnO 6 /CuI/Au configuration by optimizing the bandgap of the absorber layer up to 9.68%.…”

Formation of nanocrystalline particles on the basis of La2(Ni,Mn,Fe)2O6 variable composition phases having a structure of double perovskite under conditions of solution combustion

“…Owing to such range of properties, materials on the basis of La 2 NiMnO 6 are considered as promising for the use in spintronics [16][17][18]. Furthermore, La 2 NiMnO 6 has been extensively studied recently with regard to the use of this compound in photovoltaics [25][26][27][28][29][30].…”
