Resumo
This review investigates the stability of 2D and 3D perovskite materials for
energy conversion from solar radiation. The lower tolerance factor with
absorption wavelength at 8260 A˚ made the MAPbI3 the most popular in perovskite solar cell applications. However, these materials are affected by a
range of stability issues. The combined effect of light, moisture and oxygen can
lead to the chemical degradation of MAPbX3 perovskites. Hence, ternary
antimony/bismuth halide came into the picture in the search for stable and
nontoxic material for solar energy applications, but this material is characterized by poor photovoltaic behavior, with a higher band gap, lower dielectric
constant and higher effective mass. Another strategy by atomic transmutation
thus suggested double perovskites as potential material, with better stability,
but the band gap energy (3.3 eV) of these material is situated near the
ultraviolet (UV) range. Therefore, recent reports suggest ABS3 chalcogenides
as a potential replacement without such drawbacks. Another alternative is to
use 2D A2A0
n1BnX3nþ1 Ruddlesden–Popper perovskite materials, which show
better stability with higher efficiency than their 3D counterparts.
