The development of organic solar cells (OSCs) with thick active layers is crucial importance for the roll-to-roll printing large-area panels. Unfortunately, increasing layer thickness usually results in a significant reduction efficiency. Herein, we fabricated efficient thick-film OSCs an consisting one polymer donor and two non-fullerene acceptors. acceptors were found to possess enlarged exciton diffusion length mixed phase, which beneficial generation dissociation. Additionally, by...
Abstract A series of tetrathiophene‐based fully non‐fused ring acceptors (4T‐1, 4T‐2, 4T‐3, and 4T‐4), which can be paired with the star donor polymer PBDB‐T to fabricate highly efficient organic solar cells are developed. Tailoring size lateral chains tune solubility packing mode acceptor molecules in neat blend films. It is found that incorporation 2‐ethylhexyl effectively change compatibility PBDB‐T, an encouraging power conversion efficiency 10.15% accomplished by 4T‐3‐based cells. also...
Abstract Efficient and stable perovskite solar cells with a simple active layer are desirable for manufacturing. Three-dimensional most efficient but need to have improved environmental stability. Inclusion of larger ammonium salts has led trade-off between stability efficiency, which is attributed the films containing two-dimensional component. Here, we show that addition 0.3 mole percent fluorinated lead salt into three-dimensional methylammonium iodide enables low temperature fabrication...
The power conversion efficiencies (PCEs) of small molecule acceptor (SMA)-based organic solar cells have already exceeded 18%. However, the development polymer acceptors still lags far behind their SMA counterparts mainly due to lack efficient acceptors. Herein, a series named PY-X (with X being branched alkyl chain) are designed and synthesized by employing same central core with L8-BO but different chains on pyrrole motif. It is found that molecular packing SMA-HD featuring 2-hexyldecyl...
A transparent top anode consisting of molybdenum oxide (MoOx) and silver (Ag) is employed in an "inverted-illumination" geometry conjunction with a thick aluminium (100 nm) bottom contact. The optimised MoOx-Ag-MoOx stack (MAMS) has optical transmission 80% at the wavelength 520 nm, sheet resistance ∼5 ohm sq−1 yields conversion efficiencies 5 cm × photoactive-area "sub-modules" 3.17% - outperforming equivalent conventional ITO/PEDOT:PSS devices.
Engineering the interface between perovskite absorber and charge-transporting layers has become an important method for improving charge extraction open-circuit voltage ( VOC) of hybrid solar cells. Conjugated polymers are particularly suited to form hole-transporting layer, but their hydrophobicity renders it difficult solution-process on top. Herein, oxygen plasma treatment is introduced as a simple means change surface energy work function hydrophobic polymer interlayers use p-contacts in...
Abstract Increasing the photoluminescence quantum yield (PLQY) of narrow bandgap acceptors is critical importance to suppress nonradiative voltage loss (Δ V nr ) in organic solar cells (OSCs). Herein, two acceptors, SM16 and SM16‐R , with an identical backbone but different terminal groups (norbornenyl modified 1,1‐dicyanomethylene‐3‐indanone dimethyl substituted 1,1‐dicyanomethylene‐3‐indanone) are designed synthesized. Compared displays better solubility, higher PLQY, more favorable...
Abstract Three asymmetric non‐fullerene acceptors (LL2, LL3, and LL4) are designed synthesized with one norbornyl‐modified 1,1‐dicyanomethylene‐3‐indanone (CBIC) terminal group chlorinated (IC‐2Cl) group. The three‐dimensional shape‐persistent CBIC can effectively enhance the solubility tune packing mode of acceptors. Compared their symmetric counterparts (LL2‐2Cl, LL3‐2Cl, LL4‐2Cl) bearing two IC‐2Cl terminals, show improved solubilities, giving rise to enhanced crystallinity favored...

The high power conversion efficiencies (PCEs) of laboratory‐scale polymer‐based organic solar cells are yet to translate large area modules because a number factors including the relatively sheet resistance available transparent conducting electrodes (TCEs), and defect densities associated with thin semiconductor junctions. TCE problem limits device architectures narrow connected strips (<1 cm) causing serious fabrication difficulties extra costs. Thin junctions required poor charge...
Organic solar cells (OSCs) based on an inverted architecture generally have better stability compared to those a standard architecture. However, the photoactive area of increases under ultraviolet (UV) or illuminatiom because too-high conductivity UV-illuminated zinc oxide (ZnO) interlayer. This limits potential for industrial applications. Herein, lithium-doped ZnO (Li-ZnO) films are employed as cathode interlayer construct OSCs. The incorporation Li ions is found reduce lateral UV-treated...
Ni⁻Co alloy and Ni⁻Co⁻Y₂O₃ multiple coatings refined with nano-Y₂O₃ particles were fabricated by ultrasonic-assisted electrochemical deposition in an acid sulfamate bath. Linear sweep voltammetry (LSV), chronoamperometry (CA) impedance spectroscopy (EIS) techniques applied to investigate the nucleation/growth process of composite co-deposition. The LSV results indicated that incorporation matrix shifted initial potential a more positive decreased cathodic polarization. For both coatings,...
