Industrial-Compatible Approaches for Large-Area Flexible Perovskite Solar Cells
Flexible perovskite solar cells, known for their high flexibility, portability, and wearability, hold significant promise as the next-generation energy technology. However, transitioning from laboratory research to industrial-scale production presents numerous transitional challenges, such as scaling up production, maintaining product quality, optimizing material utilization, addressing safety concerns, and ensuring cost-effectiveness.
This article delves into the progress and practical applications of large-area flexible perovskite solar cell research, summarizing industrial-compatible approaches for their production. These methods include coating, spraying, printing, vacuum evaporation, atomic layer deposition, and magnetron sputtering. Furthermore, it discusses how manufacturing process parameters for scaled-up devices affect the performance of large-area flexible perovskite solar cells, such as substrate moving speed, annealing temperature, film thickness, environmental conditions, and perovskite precursor viscosity. Detailed discussions on material selection and preparation for each functional layer, as well as additives and interface engineering, confirm these factors as crucial for enhancing the performance of large-area flexible perovskite solar cells.
Additionally, the article introduces applications of large-area flexible perovskite solar cells in photovoltaic integrated buildings, portable devices, and aerospace, while also outlining the challenges and future development opportunities in this field.
