Abstract
Solution-processable electrodes are promising for next-generation electronics due to their simplicity, cost-effectiveness, and potential for large-area fabrication. However, current solution-processable electrodes based on conductive polymers, carbon-based compounds, and metal nanowires face challenges related to stability, patterning, and production scalability. Here we introduce a novel approach using 3D tin halide perovskites (THPs) combined with a photolithography-free solution patterning technique to fabricate solution-processed electrodes. We demonstrate the preparation of highly conductive CsSnI<sub>3</sub> films (234.9 S cm<sup>-1</sup>) and the fabrication of patterned 35 × 35 perovskite electrode arrays on a 4-in. silicon wafer. These electrodes, used as source/drain electrodes in organic transistors, resulted in devices showing high uniformity and stability. This electrode fabrication strategy is also applicable to other 3D THPs like FASnI<sub>3</sub> and MASnI<sub>3</sub>, showcasing versatility for diverse applications. The results highlight the feasibility and advantages of using 3D THPs as solution-processable electrodes, providing a new material system for the advancement of solution-processed electronics.
