Organic–inorganic hybrid lead halide perovskites have been extensively investigated for various optoelectronic applications. Particularly, owing to their ability to form highly crystalline and homogeneous films utilizing low-temperature solution processes, perovskites have become promising photoactive materials for realizing high-performance flexible solar cells. However, the current use of mesoporous TiO2 scaffolds, which require high-temperature sintering processes, has limited the fabrication of perovskite solar cells on flexible substrates. Therefore, the development of a lowtemperature processable charge-transporting layer has emerged as an urgent task for achieving flexible perovskite solar cells. This talk will address the concept of low-temperature processable electron- and hole-transporting layer materials, which contribute to improved device performance in flexible perovskite solar cells. |
