Application of quaternary Cu₂ZnSnS₄ quantum dot-sensitized solar cells based on the hydrolysis approach

Abstract

A novel synthesis and functionalization strategy for presynthesized Cu₂ZnSnS₄ QDs is developed by utilizing mercapto-acetic acid octyl ester as capping ligand. Unlike the common ligand exchange approach, the long alkyl chains are removed <italic>via</italic> hydrolysis procedure.
