Interfacial engineering in lead-free tin-based perovskite solar cells

Suppression of Nonradiative Recombination by Vacuum‐Assisted Process for Efficient Lead‐Free Tin Perovskite Solar Cells

“…Several strategies have been exploited to reduce the defect density either in the Sn‐based perovskite absorber or at the interfaces, such as compositional engineering, optimization of film morphology, interfacial engineering, design of device structure, and the use of additives to suppress oxidation of Sn 2+ or reducing Sn 4+ back to Sn 2+ . [ 26–34 ]…”

[26][27][28][29][30][31][32][33][34] Sn-based perovskites with dual FA-MA cations have been widely investigated in terms of extended absorption onset compared with the FA-only ones. Liao et al adopted a simple inverted device architecture as well as tin(II) fluoride (SnF 2 ) as additive and diethyl ether as anti-solvent to grow high-quality FASnI 3 perovskites with full coverage and high uniformity.…”

MXenes for Solar Cells

“…With the ever-increasing demand of clean and renewable energy resources [1][2][3][4], considerable attention has been devoted to the development of novel materials toward efficient solar cells [5][6][7][8][9][10][11][12][13][14]. As a family of important two-dimensional materials, MXenes, layered carbides and nitrides of transition metals first reported by the Gogotsi group in 2011 [15], which have been extensively investigated in various fields including energy storage [16][17][18][19][20][21][22], biomedical fields [23][24][25], electromagnetic applications [26][27][28][29], sensors [30][31][32][33][34], light-emitting diodes [35][36][37], water purification [38][39][40][41][42][43] and catalysis [44][45][46]…”

A Brief Review of the Role of 2D Mxene Nanosheets toward Solar Cells Efficiency Improvement

“…The development of innovative materials for efficient solar cells has garnered a lot of attention [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ] because of the ever-increasing need for renewable and clean energy supplies [ 11 , 12 , 13 , 14 , 15 ]. Sunlight has been identified as the most prevalent, cheapest, and cleanest source of energy for meeting society’s long-term energy requirements.…”
