Two-dimensional transition metal carbides (MXenes) are of great interest as electrode materials for a variety of applications, including solar cells, due to their tunable optoelectronic properties, high metallic conductivity, and attractive solution processability. However, thus far, MXene electrodes have only been exploited for lab-scale device applications. Here, to demonstrate the potential of MXene electrodes at an industry-relevant level, we implemented a scalable spray coating technique to deposit highly conductive ( ca . 8000 S/cm, at a ca . 55 nm thickness) Ti 3 C 2  T   x  films ( T   x  : surface functional groups, i . e ., -OH, -O, -F) via an automated spray system. We employed these Ti 3 C 2  T   x  films as rear electrodes for silicon heterojunction solar cells as a proof of concept. The spray-deposited MXene flakes have formed a conformal coating on top of the indium tin oxide (ITO)-coated random pyramidal textured silicon wafers, leading to &gt;20% power conversion efficiency (PCE) over both medium-sized (4.2 cm 2 ) and large (243 cm 2 , i . e ., industry-sized 6 in. pseudosquare wafers) cell areas. Notably, the Ti 3 C 2  T   x  -rear-contacted devices have retained around 99% of their initial PCE for more than 600 days of ambient air storage. Their performance is comparable with state-of-the-art solar cells contacted with sputtered silver electrodes. Our findings demonstrate the high-throughput potential of spray-coated MXene-based electrodes for solar cells in addition to a wider variety of electronic device applications.
