Herein we present a new structural design of hole-transporting material, Trux-OMeTAD, which consists C3h Truxene-core with arylamine terminals and hexyl side-chains. This planar, rigid, fully conjugated molecule exhibits excellent hole mobility desired surface energy to the perovskite uplayer. Perovskite solar cells fabricated using p-i-n architecture Trux-OMeTAD as p-layer, show high PCE 18.6% minimal hysteresis.
In this review, we first highlighted recent progress in high-performance perovskite solar cells (PVSCs) with a discussion of the fabrication methods and PVSCs-based tandem cells. Furthermore, stability issue PVSCs strategies to improve material device have been discussed, finally, summary lead-free perovskites has presented.
Abstract Increasing the power conversion efficiency (PCE) of two‐dimensional (2D) perovskite‐based solar cells (PVSCs) is really a challenge. Vertical orientation 2D perovskite film an efficient strategy to elevate PCE. In this work, vertically orientated highly crystalline (PEA) 2 (MA) n–1 Pb n I 3n+1 (PEA= phenylethylammonium, MA = methylammonium, 3, 4, 5) films are fabricated with assistance ammonium thiocyanate (NH 4 SCN) additive by one‐step spin‐coating method. Planar‐structured PVSCs...
Vertically oriented highly crystalline 2D layered (BA) 2 (MA) n −1 Pb I 3 +1 (BA = CH (CH ) NH , MA 3, 4) perovskite thin‐films are fabricated with the aid of ammonium thiocyanate (NH 4 SCN) additive through one‐step spin‐coating process. The humidity‐stability film is certified by almost unchanged X‐ray diffraction patterns after exposed to humid atmosphere ( H r 55 ± 5%) for 40 d. photovoltaic devices structure indium tin...
Two hole‐extraction materials (HEMs), TPP‐OMeTAD and TPP‐SMeTAD, have been developed to facilitate the fabrication of efficient p‐i‐n perovskite solar cells (PVSCs). By replacing oxygen atom on HEM with sulfur (from TPP‐SMeTAD), it effectively lowers highest occupied molecular orbital molecule provides stronger PbS interaction perovskites, leading charge extraction surface traps passivation. The TPP‐SMeTAD‐based PVSCs exhibit both improved photovoltaic performance reduced hysteresis in over...
Nowadays, organic solar cells (OSCs) with efficiencies over 10% have been achieved through the elaborate design of electron donors and fullerene acceptors. However, drawbacks acceptors, like poor absorption, limited chemical energetic tunabilities, high-cost purification morphological instability, become bottlenecks for further improvement OSCs. To overcome mentioned shortages from fullerene, research studies on non-fullerene acceptors boomed. date, highest efficiency fullerene-free OSCs has...
A non-fullerene acceptor ITTIC is developed for polymer solar cells with a donor PBDB-T1. high PCE of 9.12% was obtained an energy loss 0.54 eV at diminished donor/acceptor offset.
A LBG polymer is incorporated into a PTB7:PC<sub>71</sub>BM host blend to compose ternary system. Besides extending the absorption range, crystallinity and preferred face-on orientation of PTB7 are simultaneously improved. Ternary PSC 9.06% achieved with interfacial modification.
Using indole-2-carboxylic acid and vanillic as raw materials, a series of 11 novel compounds (7a–k) were synthesized by chemically linking through an aminothioureido group. The antibacterial activity these against Vibrio harveyi parahaemolyticus was evaluated using the agar perforating method. results indicated that 7g–j exhibited superior both strains compared to positive control, with 7g showing best performance. Structure-activity relationship analysis suggested alkylation nitrogen atom...

Abstract Herein three polymeric hole extraction materials (HEMs), poly(benzene‐dithiophene) (PB2T)‐O, PB2T‐S, and PB2T‐SO are presented for p–i–n perovskite solar cells (PVSCs). This study reveals that the device hysteresis performance heavily rely on grain boundary conditions. More specifically, they predetermined through molecular interaction between Lewis base atoms of HEMs perovskites. It is revealed only changing side chain terminals (OCH 3 , SCH SOCH ) results in effective...
ABSTRACT Although nanocrystals have several advantages of tunable bandgap and high carrier mobility, it is still challenging to achieve high‐performance polymer: hybrid solar cells (HSC) due the complicated surface problem. Many efforts been devoted replace long alkyl chain on improve charge transfer transport.

On the basis of atomistic simulations electrowetting single-walled carbon nanotubes by mercury, electrowettings in double-walled are studied. Classical molecular dynamics conjunction with a macroscopic electrocapillarity model carried out to clarify effect inner tube’s size on electrowetting. Results show that there is great difference between and nanotubes. The tube plays key role nanotube. Very different phenomenon occurs when changed.
