Perovskite solar cell has advanced rapidly with power conversion efficiency exceeding 24%, which makes it a promising candidate for a high-performance, low-cost photovoltaic technology. However, the large-scale perovskite solar module suffered from more serious durability problems than that of the small-area devices due to a more complex degradation mechanism introduced by iodide diffusion. It is highly desired to control the iodide diffusion process in high-efficiency perovskite devices for the realization of long-term stability. Here, we report a low-temperature solution-process-based strategy to realize stable and efficient perovskite solar modules with low-dimensional diffusion barriers. Using this strategy, the extra diffusion-induced degradation of perovskite solar modules was largely suppressed. Our findings are crucial for the design and realization of highly stable and efficient perovskite solar modules and other large-area perovskite-based optoelectronic devices.
