Alkali-metal-ion doping is an efficient strategy to improve the device performance of thin film solar cells. Though doping with Li+or Cs+doping has been reported in Ag-Bi-I solar cells, the influence of doping with other alkali metal ions on Ag-Bi-I solar cells has not been systematically studied. In this work, we investigate the effects of five alkali metal ions (Li+, Na+, K+, Rb+, and Cs+) on the structure, morphology, and optical and electrical properties of Ag2BiI5absorber layers, and also their influence on the device performance. All alkali-metal-doped Ag2BiI5thin films show high crystallinity and have similar suitable band gaps. Hall effect measurements demonstrate that the alkali-metal-doped Ag2BiI5films show an improved electrical performance compared with the pristine Ag2BiI5thin film, which is beneficial to achieving high-efficiency solar cells. Unexpectedly, Cs+doping can significantly increase the grain size of Ag2BiI5thin films, leading to a porous absorber that reduces the device efficiency. The device performance of Li+-, Na+-, K+- and Rb+-doped Ag2BiI5is significantly improved compared with that of pristine Ag2BiI5. It is found that the order of the power conversion efficiency promotion ability is K+> Rb+> Na+> Li+> Cs+under the same experimental conditions. The present approach can be extended to other Bi-based solar cells to improve their device performance, which is critical for applications in absorbers with poor electrical performance or low crystallinity.

A one?pot three?component route for the synthesis of a novel category of dithiocarbamates or xanthates is developed by a reaction of in-situ generated dithiocarbamic acids or xanthates with dialkyl azodicarboxylates under mild and catalyst-free conditions. The reaction is characterized by a wide scope, high efficiency and straightforward isolation protocol. The synthetic utility of the dithiocarbamates and xanthates was demonstrated on the preparation of symmetrical and unsymmetrical thioureas, isothiocyanates, and thiocarbamates.

A highly efficient and simple protocol for the construction of aromatic and aliphatic isothiocyanates from their respective amines in the presence of cheap, readily available, and air-stable cobalt catalyst is described. All reactions were carried out under optimized reaction conditions and gave target products in good to excellent yields within shorter reaction time.

A series of 2-(2,4-difluorophenyl)-2-hydroxy-3-(1H-1,2,4-triazol-1-yl) propyl dithiocarbamates as new analogs of fluconazole were synthesized and their antifungal activities were evaluated. Among these compounds, 2a-f and 3a-q exhibited higher activities than fluconazole against nearly all fungi tested except Aspergillus fumigatus. Noticeably, the in vitro biological activities of 2b, 3a, 3c, 3h-k, and 3o-q against Candida species were much better than those of fluconazole and ketoconazole. Also, 2a-d, 3a-d, 3e-f, 3h-k, 3p and 3q showed higher activities against A. fumi than fluconazole. Computational docking experiments indicated that the inhibition of CYP51 involved a coordination bond with iron of the heme group, the hydrophilic H-bonding region, the hydrophobic region, and the narrow hydrophobic cleft.

A series of novel dithiocarbamates with benzimidazole and chalcone scaffold have been designed synthesised and evaluated for their antimitotic activity. Compounds 4c and 9d display the most promising antimitotic activity with IC 50 of 1.66 μM and 1.52 μM respectively.
