Why is it important?

We found a novel solvent mixture for efficient dispersion and formation of smooth layer of ZnO nanoparticles. The smooth layer provided an efficient charge transport route for organic solar cells. We made uniform dispersion even in the absence of any surfactant,


Description of method for finding solvent mixture for uniform dispersion of nanoparticles provides a novel route for production of stable colloidal dispersion.
