Advances in Lead-Free Perovskite Single Crystals: Fundamentals and Applications

“…Further, Ghasemi and co-workers reported SCs of a new class of bismuth-based organohalides (phenethylammonium cation, C 8 H 12 N + , PEA + ) SCs. 194 Three kinds of crystals, (PEA) 3 Bi 2 I 9 , (PEA) 3 Bi 2 Br 9 , and (PEA) 4 Bi 2 Cl 10 were synthesized by dissolving (PEA)-halide with Bi-halide in anhydrous methanol. The transparent solution was stored in a glass vial covered with a perforated parafilm.…”

“…Metal halide perovskites (MHPs) came into significant prominence in 2012 when their intriguing optoelectronic and scientific properties were discovered. − Initially used as absorbers in dye-sensitized solar cells, they were also found to possess unprecedented charge transport properties, which sprung them into a plethora of photovoltaic applications. − Within a short period, single-cell perovskite-based photovoltaic devices have been shown to exceed 25% efficiency . Apart from solar cells, the potential applicability of perovskites in light-emitting diodes, , lasers, , transistors, , and other optoelectronic devices , has placed them on the center stage in the ever-evolving field of semiconductor physics.…”

Recent progress in morphology optimization in perovskite solar cell

“…Lewis acid-base adduct approach was developed for defect passivation, controlling grains in perovskite lms, treating grain boundaries and for suppression of non radiative recombination. [76][77][78][79][80][81] A Lewis acid with the capability of accepting a pair of nonbonding electrons has the capability to passivate electron-rich defects. J. Wang et al reported highly efficient inorganic perovskite solar cell using a Lewis base and showed the suppressed nonradiative recombination.…”

“…Son et al treated the grain boundaries in CH 3 NH 3 PbI 3 lms using Lewis acid-base adduct approach. 81 A CH 3 NH 3 I layer was formed at the grain boundaries by adding 6 mol% excess CH 3 NH 3 I to the precursor solution. Due to this excess layer at grain boundaries, non-radiative recombination was suppressed and electron-hole extraction boosted because of high ion conduction.…”

Synthesis and Characterization of a Thiophene Copolymer for Photovoltaic Application

“…Sicot and coworkers had used polythiophenes sensitized with two different dyes and measured power conversion efficiency of 0.12% (10). Recently, Satapathi et al reported polythiophene sensitized solar cells using commercially available polythiophene Poly[(9,9-dioctylfluorenyl-2,7-diyl)-co-bithiophene)] (11).…”
