Effects of triethanolamine on the formation of CZTS films using a simple dip coating technique

Abstract

CZTS films are deposited through a non-hydrazine precursor solution (with and without Triethanolamine, a stabilizing agent) by dip coating technique followed by annealing in various atmosphere. Phase formation of CZTS films as well as mechanism behind reduction of voids and porosity in the film in presence of stabilizing agent is investigated. X-Ray diffraction pattern and Raman spectra revealed the formation of kesterite structure of CZTS. SEM micrograph of CZTS film using TEA as a stabilizing agent confirms the formation of smooth, less porous, more uniform and compact film.
