Metal-halide perovskite (MHP) solar cells are continuing to break efficiency records for solution-processed solar cell devices. With over 25% power conversion efficiency, MHP solar cell are the best solution-processed devices to date. Having reached performance on par with other thin-film devices in laboratory-scale test devices, scaling MHP-based solar cells to a larger area is one of the technologically most important steps. Meantime, it requires the development and optimization of scalable process technologies, especially in ink formulations that enable reproducible coating results. A variety of scalable fabrication techniques have been successfully utilized for the deposition of MHP materials. Notably, slot-die coating is considered as one of the most promising deposition techniques in the fabrication of functional coating and solution-processed optoelectronics as uniform and compact thin-films can be processed on both rigid and flexible substrates. In this work, we demonstrated the ink optimization enable slot die coating efficient inverted perovskite solar cells.[1]
