| Abstract Scope |
Flash lamp annealing (FLA) was employed to develop highly conductive and transparent IZO/Ag/IZO oxide/metal/oxide multilayer electrodes. The transient thermal effect of FLA on the ultrathin Ag interlayer and zinc-doped indium oxide (IZO) layers was systematically investigated. Owing to its extremely short processing time, selective visible-light absorption by Ag, rapid heat transfer from Ag to IZO, and mechanical constraint imposed by the surrounding IZO layers, FLA preserved the continuity of the ultrathin Ag layer while improving the crystallinity of the IZO layers. The combination of a continuous Ag interlayer and crystalline IZO reduced visible-light scattering and promoted electron donation from the high-carrier-concentration Ag layer to the high-mobility IZO layers. The optimized IZO/Ag/IZO electrode exhibited a low sheet resistance of 4.1 Ω/sq and high optical transmittance of 90.1% over 400–800 nm. Perovskite solar cells using this electrode showed improved current generation and fill factor compared with FTO-based devices. |
