Electrochemical Performance of Photovoltaic Cells Using HDA Capped-SnS Nanocrystal from bis (<i>N</i>-1,4-Phenyl-<i>N</i>-Morpho-Dithiocarbamato) Sn(II) Complexes

Electrochemical Performance of Photovoltaic Cells Using HDA Capped-SnS Nanocrystal from bis (<i>N</i>-1,4-Phenyl-<i>N</i>-Morpho-Dithiocarbamato) Sn(II) Complexes

Great consideration is placed on the choice of capping agents&#8217; base on the proposed application, in order to cater to the particular surface, size, geometry, and functional group. Change in any of the above can influence the characteristics properties of the nanomaterials. The adoption of...
