제목 Comparative study on electrical, optical, structural properties of Ga:ZnO/Ag/Ga:ZnO and Al:ZnO/Ag/Al:ZnO multilayer electrodes for hetrojunction organic solar cells
초록 In this study, We investigated the electrical, optical, structural properties of the Ga-doped ZnO (GZO)/Ag/GZO and Al-doped ZnO (AZO)/Ag/AZO multilayer electrodes for a heterojunction organic solar cell, as a function of Ag thickness. Both GZO/Ag/GZO and AZO/Ag/AZO electrodes were deposited by in-situ dual target DC magnetron sputtering system at room temperature. The GZO and AZO films which were deposited at room temperature exhibited higher electrical resistivity and lower optical transparency than post annealed GZO and AZO films. However, we obtained the high performance multilayer electrodes with very low resistivity of ~10-5 ohm-cm and high optical transparency of >85% in visible region without the post heat treatment by inserting the thin silver layer among the GZO and AZO layer. In addition, we fabricated the heterojunction organic solar cell using the optimized GZO/Ag/GZO and AZO/Ag/AZO multilayer electrodes. It showed the power conversion efficiency of GZO/Ag/GZO of > 2.5% and AZO/Ag/AZO of <1%, respectively.
