It is noted that Cs is also a key element for lead-free halide cesium tin iodide (CsSnI 3) perovskite solar cells. High short-circuit current densities could be attained due to the smaller bandgap of Sn-based perovskite [50 –52]. Although the open circuit voltage was limited by bulk recombination, the bottleneck was recently overcome by doping of CsSnI 3 with Br

To date, the best perovskite solar cells use mixed organic cations (methylammonium (MA) and formamidinium (FA)) and mixed halides. Unfortunately, MA/FA compositions are sensitive to processing conditions because of their intrinsic structural and thermal instability.
Moreover, perovskite materials have shown potential for solar-active electrode applications for integrating solar cells and batteries into a single device. However, there are significant challenges in applying perovskites in LIBs and solar-rechargeable batteries.
Furthermore, by substituting the iodine with bromine and chlorine ions, it is possible to increase the value of the Goldsmith factor and consequently improving the stability of the perovskite cubic phase (Figure 7B).
