Lead‐Free Perovskites: Metals Substitution towards Environmentally Benign Solar Cell Fabricationelectro-optical propertieslead-freemetal substitutionperovskitesolar cellsPerovskite solar cells have attracted significant attention during the current decade owing to their efficacy and photovoltaics performance, which ...
Filip et al. considered stability and desired bandgap as two concurrent prerequisites for suitable candidates of lead-free perovskites [66]. They used randomly displaced structures (atom positions and lattice parameters) to investigate the stability of possible lead-free perovskites. Making the stability...
structure dimensions. Finally, the applications of lead-free perovskites in solar cells, light-emitting diodes, and X-ray detectors were examined. This review also provides suggestions for future research on lead-free perovskites. 摘要 卤化铅钙钛矿由于具有高吸收系数、高载流子迁移率、高 缺陷容忍度和高...
Lead halide perovskites have attracted extensive attention in recent years because of their excellent photoelectronic properties, such as high absorption coefficients, carrier mobilities, defect tolerances, and photoluminescence efficiencies. However, a key issue hindering their commercial application is the tox...
A class of materials called perovskites has emerged as a promising alternative to silicon for making inexpensive and efficient solar cells. But for all their promise, perovskites are not without their downsides. Most contain ...

A machine learning approach employing a generalized element゛gnostic fingerprint is shown to rapidly and accurately predict key properties using a new database of 344 perovskites generated with density functional theory. Bandgap, formation energy, and convex hull distance are predicted using validation ...
After only a few years of research, it is clear that perovskites will play a major role in the future energy scenario. The last step is the removal of lead from the perovskite composition to meet the worldwide-adopted restriction of the use of hazardous substances. Here, we provide a ...
Lead-free perovskites for flexible optoelectronics 2024, Materials Today Electronics Citation Excerpt : Consequently, they can generate a higher short-circuit current density (Jsc) and closely approach the theoretical Shockley–Queisser efficiency limit [74]. The attractiveness of Sn as an alternative mat...
Nevertheless, trade-off towards commercialization exists between nontoxicity and high performance, with the poor stability of lead-based perovskites, indicating that it is indispensable to substitute lead with nontoxic element meanwhile bring about a comparable figure of merit of photodetectors and ...
