초록
Hybrid organic-inorganic perovskite solar cells (PSCs) are promising candidates for next- generation photovoltaics due to their excellent performance, flexibility, and low-cost production. Despite these advancements, significant challenges remain, particularly concerning long-term stability and scalability, which are critical for commercialization. The primary stability issues stem from the degradation of perovskite materials, resulting in reduced light absorption and increased defects. Although progress has been made in developing more stable materials and effective encapsulation techniques, achieving long-term durability for PSCs remains challenging. This review identifies five major factors causing perovskite degradation and explores the underlying mechanisms: exposure to light, oxygen, moisture, ion migration, thermal instability, and mechanical deformation. Addressing these issues is crucial to improving the stability and commercial viability of PSCs and other perovskite-based optoelectronic devices.
