Lithium chloride-based interface engineering at electron transport and perovskite layers to boost the performance of perovskite photovoltaics

Introduction of cadmium chloride additive to improve the performance and stability of perovskite solar cells

“…As demonstrated, multiple main XRD peaks at 13.82 , 20.10 , 28.18 , and 31.59 were indexed as (110), (112), (220), and (310) planes of the tetragonal MAPbI 3 phase, respectively. 21 The sharp and intensive peaks in the XRD plots of the MAPbI 3 perovskites implied that the lms were well crystallized. Furthermore, the intensities of the prominent peaks all rose when the CdCl 2 solvent was incorporated, implying that a superior crystalline nature and larger crystallite size for perovskite lm were developed as compared to a lm prepared without CdCl 2 .…”

“…16,17 To date, several ways of controlling perovskite morphology have been explored, involving manipulating the deposition method, additive engineering, interfacial engineering, and compositional engineering. [18][19][20][21][22] Additive engineering has been shown to be effective in improving the quality of the perovskite layer since it is a more simple and reproducible approach. Some agents, including copper chloride, N,1-diiodoformamidine, potassium hexauorophosphate, formamidine acetate salt, etc., can form an intermediate phase with perovskite precursors, which could regulate the dynamic process of crystal formation and thereby minimize GBs.…”

Numerical investigation of single junction environmental friendly double perovskite ( Cs 2 AuBiCl 6 ) solar cell with 20.5% power conversion efficiency and negligible hysteresis

“…We have taken two different defect models to study the ion migration phenomenon. [44][45][46][47] In the first model, we have considered defects present at interfacial traps (n + /i and i/p + ) at the junction. In the second model, defects present in the vicinity of the n+ and p+ layer near the junction are considered for hysteresis analysis.…”

“…This phenomenon is characterised by ion migration, ion accumulation at junctions, and ion accumulation at the junction interfacial areas. We have taken two different defect models to study the ion migration phenomenon 44‐47 . In the first model, we have considered defects present at interfacial traps (n + /i and i/p + ) at the junction.…”

SnO2@ZnO nanocomposites doped polyaniline polymer for high performance of HTM-free perovskite solar cells and carbon-based

“…However, the SnO 2 nanoparticles, due to van der Waals interactions between nanoparticles, tend to form large agglomerates spontaneously 15 . The interface between the electron transfer layer and the perovskite usually requires a modification process to increase the performance of the PSC 16 . The well-developed perovskite films include inactivated grain boundaries (GBs), large-sized crystal growth, high crystallinity, and low density of trapped defect.…”
