“…The results in this study have confirmed that selenylation started approximately 1.5 min after moving the RPT furnace to the right place. The process can be depicted by the Fick's second law, which is given by:

N_{{Se}_{s}} (x {,t) = (N}_{{Se}_{normals}})_{s} \times false[1‐erf \frac{x}{2 \sqrt{D (T) \times (t‐1.5)}}]

where

N_{S {normale}_{s}} (x, t)

is the concentration of Se,

{{(N}_{S {normale}_{s}})}_{s}

is saturation concentration of Se, x is normalized distance to the top of the film, and D is the diffusion coefficient assumed only dependent on the temperature. Referred to EDX measurement, we can confirm that almost all of Sb 2 S 3 could be conversed to Sb 2 Se 3 if the selenylation time is long enough, and

{{(N}_{S {normale}_{s}})}_{s}

could be seemed as 1.…”

Antimony chalcogenide is a promising absorber material for photovoltaic (PV) cells because of its tunable band gap, strong optical absorption, earthabundant, and nontoxic constituents. Here, a novel hydrazine-free approach for fabricating antimony chalcogenide films prepared via spray pyrolysis deposition with further selenylation, as well as high performance solar cells are reported. The fabricated antimony chalcogenide solar cells exhibits remarkably high open-circuit voltage (V OC ) comparing with that of Sb 2 Se 3 and Sb 2 S 3 devices. The distribution of Se during the selenylation process via refering to the Fick's second law is discussed. The results show that the selenized absorber has tremendously improved absorbance for visible light and a cascade-type energy level from surface to bulk, resulting in an ideal energy level matching for p-n junction. By introducing an efficient buffer layer, the detrimental short-circuit is avoided by reducing the cracks. Finally, 4.57% of the power conversion efficiency (PCE) of the solar cell is achieved. Furthermore, a module with a large-scale active area of 21 cm 2 is successfully fabricated, which shows a PCE of 3.19%, and a V OC of 3.42 V. The present work suggests that the antimony chalcogenide solar cells are promising for industrial application.

Ordered mesoporous carbon materials were prepared by doping boric acid using a hardtemplating method. The capacitive performance of these carbons was investigated in organic and H2SO4 electrolytes. As demonstrated by structure analysis the prepared carbons possessed parallel mesoporous channels. The pore size increased from 3.3 to 5.7 nm and the molar fraction of oxygenated groups on the carbon surface increased from 2.0% to 5.2% with an increase in the amount of boric acid doping from 0 to 50% (molar fraction). In the organic electrolyte, the carbons mainly showed typical electric double layer capacitive performance and no visible pseudo-capacitance was induced. In H2SO4 electrolytes, BOMC-5 showed the highest specific mass capacitance of 140.9 F•g-1 and the specific surface capacitance of the prepared carbons increased with an increase in the oxygenated groups and this carbon showed visible pseudo-capacitance because of the rapid redox reactions of the oxygenated groups. The capacitance retention ratio depends on the surface chemical properties, which determines the wettability of the carbon surface and the electrolytes.

“…We have been particularly interested in double‐cable conjugated polymers for application in SCOSCs since they could be synthesized via a controllable manner, in which a series of functionalized monomers with pendent electron acceptors were prepared for palladium‐catalyzed polymerization [11] . This enabled us to incorporate the widely reported conjugated polymers and electron acceptors into double‐cable polymers, providing tunable optical and electrical properties [7h–m, 12] . Among them, we found that the linear conjugated backbones [7h] and post‐thermal treatment [7i] could facilitate the simultaneous self‐assembly of conjugated backbones and aromatic side units, generated well‐ordered nanophase separation, and hence provided external quantum efficiencies (EQEs) above 0.65 and PCEs over 6 %.…”

Arecordpower conversion efficiency of 8.40 %was obtained in single-component organic solar cells (SCOSCs) based on double-cable conjugated polymers.T his is realized based on exciton separation playing the same role as charge transport in SCOSCs.T wo double-cable conjugated polymers were designed with almost identical conjugated backbones and electron-withdrawing side units,b ut extra Cl atoms had different positions on the conjugated backbones.W hen Cl atoms were positioned at the main chains,the polymer formed the twist backbones,e nabling better miscibility with the naphthalene diimide side units.T his improves the interface contact between conjugated backbones and side units,resulting in efficient conversion of excitons into free charges.T hese findings reveal the importance of charge generation process in SCOSCs and suggest as trategy to improve this process: controlling miscibility between conjugated backbones and aromatic side units in double-cable conjugated polymers.
