Developing a transparent and cost-effective electrode for a textured and large-scale optoelectronic device is an important requirement for high-throughput products. Here, we propose a costly fabrication procedure using reduced graphene oxide (rGO) hybrid materials composed of rGO, Au nanoparticles (AuNPs) and Ag nanowires (AgNWs) top electrodes for structured Si solar cells via a spin coating method. This work overcomes the obstacle of graphene damage during the transferred process and provides a simple way to form largescale graphene-based films on textured surfaces. Due to the spin-coated rGO being uniform along with AgNW frameworks and plasmonic AuNPs, the pyramidal Si solar cell exhibits a significant improved efficiency of 10.75% compared with solar cells using pure rGO flakes as the top electrodes. Our study realizes the rGO hybrid materials deposited on a textured surface and has great potential for integration into transparent and structured devices for nextgeneration industrial production.
