Abstract
Ethanolamine was used to complex a metal (Cu, Zn, Sn)-ethanolamine from copper (II) acetate monohydrate, zinc acetate dehydrate and tin (II) chloride dehydrate. Calcination and sulfurization of the spin coated metal (Cu, Zn, Sn)-ethanolamine precursor were conducted to form kesterite Cu2ZnSnS4 (CZTS) thin films adhesive to the substrate. The optical-electrical properties of the films exhibited p-type semiconductivity with a mobility and resistivity of 7.64 cm(2)/Vs and 3.78 Omega cm, respectively, and a band gap of 1.52 eV with an absorption coefficient > 10(5) cm(-1) at a copper-poor, zinc-rich composition of Cu/(Zn+Sn) = 0.83, Zn/Sn = 1.76 and S/metal = 1.08. Using metal (Cu, Zn, Sn) ethanolamine at the chemical bath deposition process, a CZTS thin film suitable for solar absorber layer applications was fabricated.
