Thermal effect on CZTS solar cells in different process of ZnO/ITO window layer fabrication
Abstract
In this work, a window layer consisting of zinc oxide (ZnO) and indium‑tin-oxide (ITO) thin films was prepared by sputtering under different heat treatment processes (<em>in-situ</em> or post annealing) to study the effect on structural ordering and performance of Cu<sub>2</sub>ZnSnS<sub>4</sub> (CZTS) solar cells. It is found that all characteristic performance parameters including open circuit voltage (V<sub>oc</sub>), short circuit current density (J<sub>sc</sub>), fill factor (FF) and efficiency of CZTS solar cells were improved for the window layer with ITO thickness = 350 nm post-annealed at lower temperature. Specifically, V<sub>oc</sub> of the CZTS device was increased by 57 mV when the window layer was post-annealed at 200 °C (V<sub>oc</sub> = 585 mV) compared to the device with window layer made at 300 °C (V<sub>oc</sub> = 528 mV). We further reduced the thickness of the window layer with ITO thickness = 140 nm which was deposited in an <em>in-situ</em> annealing process at 220 °C. Compared to the 350 nm thick film made by post-annealing, it is found that the thin film made by <em>in-situ</em> annealing help to further boost the V<sub>oc</sub> (equals 635 mV) and thus efficiency (3.20%) of CZTS solar cells. Study of the evolution of full width half maximum (FWHM) and intensity ratio (Q) of major Raman scattering peaks of CZTS indicates a much reduced structure disorder in the CZTS material with ZnO/ITO window layer annealed at low temperature. Further analysis of the evolution of diode ideality factor (A), reverse saturation current density (J<sub>0</sub>) and Urbach energy (E<sub>u</sub>) of these devices revealed that the quality of bulk CZTS and/or CZTS/CdS heterojunction were more degraded at higher temperature. However, the <em>in-situ</em> annealing provided extra benefits to device performance which is possibly due to modification of interfacial properties of CZTS/CdS and/or CdS/ZnO.
