Abstract

SnS2 has adequate properties for photovoltaic applications in solar cells. For this purpose, we studied the influence of the capping agents pyridine and aniline in the nanoparticles hydrothermal syntheses. These capping agents are suitable for use in hybrid organic- inorganic solar cells. Different ratios of these agents with respect to the metal precursor were tested. Hexagonal and disc-type nanoparticles were obtained. Lower concentrations of capping agent increased the proportion of hexagons, while diminishing their size. The obtained products are adequate in size, dispersion of size, and stabile in suspension in chloroform to use them in hybrid solar cells. Moreover, the use ofpyridine allowed for more stable suspensions, and therefore better results for this application.
