Cu2ZnSnS4(CZTS) presents itself as a potential quaternary semiconductor absorber layer in the field of thin film heterojunction solar cells. The conventional spray pyrolysis method has been used in the present investigation. X-ray diffraction results confirm the structure of the deposited films as kesterite. The lattice parameters are determined to be a = 0.5436 nm and c = 1.0856 nm. The material exhibits an energy gap of 1.5 eV and an optical absorption coefficient exceeding 104/cm. CZTS films exhibit a p-type nature. The deposited films are kept on the hot surface for some time after the chemical spray pyrolysis is finished, which contributes to improved crystallinity. Using chemical synthesis techniques, a Cu2ZnSnS4 thin film solar cell is constructed. These solar cells exhibited an efficiency of 0.5%. Ongoing efforts are directed towards achieving reasonable efficiency levels. [ABSTRACT FROM AUTHOR] |
