6 Frequently Asked Questions about “Perovskite cells require antimony film”
Can antimony be substituted with a layered perovskite?
The exploration of partial substitution involving antimony (Sb) has been investigated. This was illustrated through the creation of a layered perovskite, denoted by the formula Cs 4 CuSb 2 Cl 12. In this compound, a single Sb 3+ ion is replaced with Cu 2+.
What diffraction peaks in a perovskite film with antimony?
The diffraction peaks at 28.25° for the perovskite film can be indexed to the (002) plane. The lattice distance is 0.315 nm, which matches well with that of the (012) plane of ANs. The morphology of the perovskite film with antimony is subsequently investigated and shown in Fig. 2 b.
Can antimony regulate the growth of crystalline iodine-based perovskite crystalline lattices?
However, all-inorganic iodine-based perovskites generally exhibit poor phase stability in ambient conditions. Herein, we propose an efficient strategy to introduce antimony (Sb 3+) into the crystalline lattices of CsPbI 2 Br perovskite, which can effectively regulate the growth of perovskite crystals to obtain a more stable perovskite phase.
What is the spatial distribution of a perovskite film with antimony?
The spatial distribution of the perovskite film with Sb is investigated by energy dispersive X-ray spectroscopy (EDS) on the TEM. As shown in Fig. S2, the EDS mapping shows the distributions of Sb, I, N, and Pb elements in the perovskite film with antimony.
Can antimony-based perovskites improve PV performance?
Antimony-based perovskites have lately grabbed the attention of PV research communities. However, developing a stable and reliable Sb-based perovskite for enhanced PV performance necessitates optimizing methods such as doping, material engineering, stoichiometry, and adjustments to lattice dimensions.
Are antimony-based perovskite materials safe?
However, there is an urgent call for alternative perovskite materials with toxicity levels and poor stability to UV radiations. Antimony-based perovskites have proven to be a material with unique optoelectronic properties, conventional fabrication processes, low-toxicity levels and high stability values.
