چکیده انگلیسی
Preparing transparent conducting oxide (TCO) layer is one of the critical procedures for the fabrication of CIGS solar cells. Especially conventional fabrication of TCO requires elevated temperature annealing process, which causes fatal effect for flexible CIGS solar cell grown on polyimide (PI) substrate. In this paper, we investigated the preparation method of aluminum-doped zinc oxide (AZO) and tin-doped indium oxide (ITO) bilayer thin films as the window layer by DC magnetron sputtering without annealing process. By varying the thickness of AZO and ITO, the bilayer thin films with high optical transmittance (>81.5% from 400â¯nm to 1200â¯nm) were achieved. The formation of ITO grains on AZO layer was analyzed by XRD and AFM. When the AZO thickness reached to 150â¯nm, an AZO-assisted ITO growth phenomenon was observed in our experiment, which was important for improving the electrical properties of bilayer structure. Compared to single layered (AZO or ITO) structure, the CIGS solar cells using bilayer structure enhanced photoelectric conversion efficiency (â¼above 11%) and long-term stability.
