It is revealed that etching takes place stepwise. In very beginning stages etching take place due to decomposition and removing CH 3 and NH 3 molecules from perovskite crystal lattice. Further treatment involves water molecules to the etching process which dramatically changes microstructure and forms spherical particles. For patterning the
This study demonstrates the use of perovskite solar cells for fabrication of self-charging lithium-ion batteries (LIBs). A LiFePO 4 (LFP) cathode and Li 4 Ti 5 O 12 (LTO) anode were used to fabricate a LIB. The surface morphologies of the LiFePO 4 and Li 4 Ti 5 O 12 powders were examined using field emission scanning electron microscopy. The structural
Air-processed perovskite solar cells are desirable for the large-scale manufacturing application in the future, yet the presence of moisture and oxygen goes against perovskite crystallization and deteriorates phase stabilization, leading to the formation of substantial defective nano-impurities, especially on the vulnerable surface.
Residual stresses generated within perovskite films during the high-temperature annealing and cooling process are the key contributors to the reduction of device performance and lifespan deterioration. Herein, a strategy
Perovskite solar cells (PSCs) have attracted significant interest over the past few years because of their robust operational capabilities, negligible hysteresis and low-temperature fabrication processes .The ultimate goal is to enhance the power conversion efficiency (PCE) and accelerate the commercialization, and upscaling of solar cell devices.

An organic-inorganic hybrid methyl ammonium lead iodide (CH 3 NH 3 PbI 3) perovskite films is deposited and etched using atmospheric plasma treatment method. Among oxygen, nitrogen and hydrogen gases hydrogen is selected as an effective way for etching the perovskite film. It is revealed that etching takes place stepwise.
In this paper results on chemical etching of some substrates with perovskite, ABO3, structure (e.g., SrTiO3, LSAT -the (LaAlO3)0.3 (Sr2AlTaO6)0.35 solid solution, and NdGaO3) are presented. In order to obtain high quality substrates, different etchants (NH 4 F + HF, HCl + NH4Cl, and HCl + HNO3) with various pH values have been studied.
As a thicker perovskite is coated or deposited onto the patterned substrate, the formed structure will be patterned coarsely. Recently, we have reported direct patterning on perovskites using focused-ion beam (FIB) etching.
(18) Because perovskites are a hybrid organic–inorganic material, we specifically selected XeF 2 and I 2 as the chemical precursors for our GAFIB etching. These precursors have been previously shown to enhance etching (2–5 magnitudes) for PMMA (which is an organic material).
It is clear that in the region 4 the perovskite is fully etched. As summary SEM and EDS also confirm that hydrogen plasma treatment is an effective way for etching perovskite film. It is expected that the static magnetic field created by the magnet may influence on plasma formation.
However, owing to the sensitivity of organic moieties to solvents and temperature, device processing is challenging, particularly for patterning. Here, we report the direct patterning of perovskites using chemically gas-assisted focused-ion beam (GAFIB) etching with XeF 2 and I 2 precursors.
