  4. Abstract:
  5. Targeting on the selenium free, pure sulfide kesterite compound (CZTS) allows retention of the higher band gap nontoxic absorber for a single-junction solar cell. In this work, CZTS thin films were deposited by the PLD method and the Structural/optical properties, as well as Mott–Schottky analysis, were studied at different substrate temperatures. Without undergoing the sulfurization process, the single-phase CZTS thin film is prepared at 300 ℃. In the second step, a numerical simulation is performed using the solar cell capacitance simulator to study the effect of the grading layer of MoS(Se)2 on the rear side of pure sulfide kesterite based solar cells. The device with a MoSe2 coated substrate exhibits better performance in comparison with the soda-lime-glass (SLG)/Mo that is susceptible to the formation of an n-type MoS2 intermediate layer. An improvement in conversion efficiency from 5.4% to 13.99%, often due to an increase of open-circuit voltage has been reached. © 2020 Elsevier B.V
