Abstract:
Sphalerite-type (Cu(2)Sn)(x/3)Zn(1-x)S (0 < or = x < or = 0.75) nanocrystals with tunable band gaps were successfully prepared via a solvothermal approach. Band gaps of the nanoparticles could be adjusted from 3.48 eV to 1.23 eV by changing the composition. Their implementation in quantum dot sensitized solar cells (QDSSCs) suggests considerable potential in solar cells.
