Toward Long-Term Stable and Highly Efficient Perovskite Solar Cells via Effective Charge Transporting Materials

Perovskite solar cells (PSCs) have advanced quickly with their power conversion efficiency approaching the record of silicon solar cells. However, there is still a big challenge to obtain both high efficiency and long-term stability for future commercialization of PSCs. The major instability issue is associated with the decomposition or phase transition of perovskite materials that are believed to be intrinsically unstable under outdoor working conditions. Herein, the authors review the approaches that marked important progress in developing new functional electron/hole transporting materials that enabled highly efficient and stable PSCs. The findings that accelerate charge diffusion and that suppress the irrevocable loss of ions diffusing out of perovskite materials and other diffusion processes are highlighted. In addition, derivative interface engineering methods to control the diffusion process of charges/ions/molecules are also reviewed. Finally, the authors propose key research issues in charge transporting materials and interface engineering with regard to the important diffusion processes that will be one of the keys to realize highly efficient and long-term stable PSCs.

Discrete Supertetrahedral T5 Selenide Clusters and Their Se/S Solid Solutions: Ionic-Liquid-Assisted Precursor Route Syntheses and Photocatalytic Properties

Although supertetrahedral Tn sulfide clusters (n=2?6) have been extensively explored, the synthesis of Tn selenide clusters with n>4 has not been achieved thus far. Reported here are ionic-liquid (IL)-assisted precursor route syntheses, characterizations, and the photocatalytic properties of six new M-In-Q (M=Cu or Cd; Q=Se or Se/S) chalcogenide compounds, namely [Bmmim]12Cu5In30Q52Cl3(Im) (Q=Se (T5-1), Se48.5S3.5 (T5-2); Bmmim=1-butyl-2,3-dimethylimidazolium, Im=imidazole), [Bmmim]11Cd6In28Q52Cl3(MIm) (Q=Se (T5-3), Se28.5S23.5 (T5-4), Se16S36 (T5-5); MIm=1-methylimidazole), and [Bmmim]9Cd6In28Se8S44Cl(MIm)3 (T5-6). The cluster compounds T5-1 and T5-3 represent the largest molecular supertetrahedral Tn selenide clusters to date. Under visible-light illumination, the Cu-In-Q compounds showed photocatalytic activity towards the decomposition of crystal violet, whereas the Cd-In-Q compounds exhibited good photocatalytic H2 evolution activity. Interestingly, the experimental results show that the photocatalytic performances of the selenide/sulfide solid solutions were significantly better than those of their selenide analogues, for example, the degradation time of the organic dye with T5-2 was much shorter than that with T5-1, whereas the photocatalytic H2 evolution efficiencies with T5-3?T5-6 improved significantly with increasing sulfur content. This work highlights the significance of IL-assisted precursor route synthesis and the tuning of photocatalytic properties through the formation of solid solutions.

Bisamidate Prodrugs of 2-Substituted 9-[2-(Phosphonomethoxy)ethyl]adenine (PMEA, adefovir) as Selective Inhibitors of Adenylate Cyclase Toxin from Bordetella pertussis

Novel small-molecule agents to treat Bordetella pertussis infections are highly desirable, as pertussis (whooping cough) remains a serious health threat worldwide. In this study, a series of 2-substituted derivatives of 9-[2-(phosphonomethoxy)ethyl]adenine (PMEA, adefovir), in their isopropyl ester bis(L-phenylalanine) prodrug form, were designed and synthesized as potent inhibitors of adenylate cyclase toxin (ACT) isolated from B. pertussis. The series consists of PMEA analogues bearing either a linear or branched aliphatic chain or a heteroatom at the C2 position of the purine moiety. Compounds with a small C2 substituent showed high potency against ACT without cytotoxic effects as well as good selectivity over human adenylate cyclase isoforms AC1, AC2, and AC5. The most potent ACT inhibitor was found to be the bisamidate prodrug of the 2-fluoro PMEA derivative (IC50=0.145 muM). Although the bisamidate prodrugs reported herein exhibit overall lower activity than the bis(pivaloyloxymethyl) prodrug (adefovir dipivoxil), their toxicity and plasma stability profiles are superior. Furthermore, the bisamidate prodrug was shown to be more stable in plasma than in macrophage homogenate, indicating that the free phosphonate can be effectively distributed to target tissues, such as the lungs. Thus, ACT inhibitors based on acyclic nucleoside phosphonates may represent a new strategy to treat whooping cough. Whooping cough combatted: With the aim to establish a new strategy against pertussis, C2-modified adefovir analogues in their bisamidate prodrug form were found to efficiently inhibit adenylate cyclase toxin (ACT) from Bordetella pertussis. The compounds show favorable plasma stability, effective distribution to target tissues, and good selectivity for ACT over human adenylate cyclase isoforms.

Colloidal CZTS nanoparticles and films: Preparation and characterization

Cu2ZnSnS4 (CZTS) compound semiconductor has the advantage of good matching with solar radiation in optical band-gap, large absorption coefficient, non-toxic and especially large abundance ratios of elements, so that CZTS has been considered as a good absorber layer used for the thin-film solar cells with most industrialization promising and environment friendly. In the present work, colloidal CZTS nanocrystals (average size ~8-16 nm) with the band gap of ~1.5 eV were synthesized via wet-chemical processing, using oleylamine (OLA) as solvent and capping molecules. The colloids were characterized by X-ray diffraction (XRD), Raman spectroscopy, transmission electron microscopy (TEM), scanning electron microscopy (SEM) and UV-Vis-NIR spectroscopy. The structure and morphology of nanocrystals were influenced with the reaction temperature. The resulting nanocrystals were kesterite-phase CZTS when the reaction temperature was lower, but were wurtzite-phase CZTS when the reaction temperature above 275 C. The CZTS films on glass substrates were prepared by drop-casting, from the colloidal 10 wt% CZTS-toluene solution where the CZTS colloids were synthesized at 260 C with three different recipes. The resulting films with different heat-treatments were investigated by XRD, SEM and energy dispersive spectroscopy (EDS). Densified CZTS films (5 lm in thickness) could be obtained by drying and sintering in vacuum. The CZTS films have the band-gap around 1.6-2.0 eV, due to Zn rich and S poor in the films. The dark conductivity and photoconductivity under AM 1.5 irradiation of the CZTS films on ITO glass substrates with different heat-treatments were measured by the AC impedance method.

Photovoltage study of charge injection from dye molecules into transparent hole and electron conductors

The investigation of transient and spectral photovoltage (PV) for charge injection from a dye [Ru(dcbpyH2)2(NCS)2] into transparent hole (CuSCN, CuI, CuAlO2) and electron (TiO2, SnO2:F) conductors was discussed. Depending on the transparent hole or electron conductor and on the mechanism of charge separation, the PV signal rises to a maximum within 10 ns to 10 mus. It was shown that the efficiency of hole and electron injection was of the same order while the effective lifetimes of injected charge vary between several mus and 1 ms for the samples used. It was shown that a 1000 W Xe-lamp with a quartz monochromator provided light in the range of 0.4 to 4.5 eV for PV spectra.

Copper(II) and zinc(II) complexes with Hydrazone: Synthesis, crystal structure, Hirshfeld surface and antibacterial activity

The present study reports the synthesis and characterization of six Cu(II) and Zn(II) complexes with 2-cetylpyridinenicotinichydrazone (HL). The characterization of the complexes were applied by conductivity measurements and spectroscopic techniques (FT-IR, UV?Vis, ESI(+)-MS and NMR 1H). Four complexes have been studied by single crystal X-ray diffraction, [Cu(L)2] (1), [Zn(L)2] (2), [CuCl2(HL)] (3) and [CuBr2(HL)] (4). Important interactions upon the molecular packing were also performed by the analysis of their Hirshfeld surfaces and compared to the 2D-fingerprint plots. The characterizations indicates the formation of mononuclear Cu(II) and Zn(II) complexes with the hydrazone ligand coordinated to the metal ions in tridentate mode through the NNO chelating system. The antibacterial activity of HL and its metal complexes was tested against cariogenic bacteria strains.
