“…The first element considered for lead replacement was tin, which occurs in the same periodic group as lead (G14 element), offering an energy gap of 1.3 eV for MASnI 3Àx Br x . [87,[422][423][424] However, MASnI 3Àx Br x showed extremely low stability (80% performance retention after 12 h in N 2 condition) with an initial PCE of 5.73%. [87] Studies are also reported replacing lead with germanium (Ge, G14 element), resulting in MAGeI 3 with an energy gap of %2.0 eV and PCE of 0.57%, with low stability as well.…”

Perovskite solar cells (PSCs) have received a large amount of research funds due to their potential as a frontrunner in a new generation of solar cells; consequently, the desire to commercialize this technology is mounting. In this roadmap, the knowledge and the technological gaps between laboratory and industry are critically analyzed from the perspective of 5S criteria (Stability, Safety, Sustainability, Scalability, and Storage). To avoid any favoritism in the arguments toward commercializing this technology, herein, the average parameters of PSCs (photoconversion efficiency, durability, cost, manufacturability, and sustainability) estimated from previous studies are analyzed and discussed. Unique opportunities for PSCs in their current stage of achievements are identified, where application‐driven, instead of performance‐driven, developments are shown to favor their commercialization. Efforts required to improve the average performance of PSCs to state‐of‐the‐art levels are also identified and discussed.

“…By forming of the strong hydrogen bonding between halide ions in the perovskite by using aminoguanidine hydrochloride (NH 2 GACl) as the coadditive in a perovskite precursor, defects in the perovskite crystals were passivated and energy‐level alignment occurred between the resultant perovskite and the corresponding charge carrier layers. [ 78 ] A successful surface‐controlled growth of FASnI 3 was obtained by introducing 2 mole% pentafluorophen‐oxyethylammonium iodide (FOEI). Highly oriented and smooth FASnI 3 –FOEI perovskite films with a longer charge‐carrier lifetime were fabricated.…”

Mixed halide perovskite compounds with the formula AMX 3 (A þ ¼ CH 3 NH 3 (MA)/HC(NH 2) 2 (FA)/Cs/Rb; M 2þ ¼ Pb, Sn; X À ¼ Cl, Br, I) have emerged as a potential material for fabrication of next-generation solar cells with high photovoltaic performance. [1] A recent study has shown that perovskite solar cells (PSCs) can be fabricated with a high power conversion efficiency (PCE) of 25.5% with Pb as the divalent metal in the compound. [2] Unfortunately, the presence of toxic Pb remains questionable for largescale production. Fortunately, Sn, which is located above Pb in group IV of the periodic table of elements, is a promising candidate for harmless photovoltaic applications. Compared to Pb, Sn is less toxic and can form perovskite compounds with various cations. Sn-based perovskite compounds possess fascinating properties for solar cell applications, such as a narrower bandgap, a lower exciton binding energy, a high charge carrier mobility, and a slightly smaller radius than Pb 2þ , which allows for the replacement of Pb by Sn while retaining the perovskite structure. Notably, the Sn-perovskite materials possess an optimal bandgap for solar cell applications between 1.1 and 1.4 eV and can be decomposed to nontoxic materials such as Sn II oxide (SnO 2). [3] However, fabricating high-quality Sn-based perovskite films is still unmanageable due to the lack of a basic understanding of the Sn II compounds. Such lacking hinders the potential realization of the corresponding film properties, such as surface morphology, pinhole-free layer formation, and low crystallinity. Until now, the most successful of the Sn-PSCs have been fabricated with FASnI 3 as the absorber layer.
