6 FAQs about [Does perovskite photovoltaic cells use cesium ]
How does cesium affect the performance of a perovskite solar cell?
At a higher concentration (x > 0.1), cesium reduces the performance of the perovskite solar cell. It can be caused by a reduction in the size of the crystallites for perovskite with a Cs concentration larger than 10% (see Table 1) which induced the growth of carrier recombination rate. 4. Conclusions
Which cations are used in perovskite solar cells?
Currently, the best perovskite solar cells use a mixture of formamidinium (FA) and methylammonium (MA) as the monovalent cations [35, 36, 37, 38, 39, 40, 41]. Thea addition of cesium makes the triple cation perovskite compositions more thermally stable, as they have less phase impurities and are less sensitive to processing conditions [27, 35].
Will perovskite solar cells be commercial?
Recently, since the efficiency of the best perovskite solar-cell reached 25.5%, comparable to the best PV cells made of single-crystal silicon, it is optimistic for the perovskite PV cells to be commercial in the future.
Can perovskite films produce high-performance solar cells (PSCs)?

The morphology and quality of the inorganic film in the first step play pivotal roles in depositing high-performance PSCs.
What are CSAC-doped perovskite solar cells?
The CsAc-doped perovskite solar cells were thus fabricated. Since the introduction of CsAc into perovskite is conducive to the formation of high-quality films, the PbI 2 precursor without CsAc is named the pristine films, and the one treated by CsAc is named the CsAc-doped films. Fig. 1.
Are perovskite solar cells recyclable?
Another core problem in the development, production and use of perovskite solar cells is their recyclability. Perovskite recycling is an absolute necessity due to the presence of lead in perovskites.
