Role of barrier films in maintaining the stability of perovskite solar cells

Flexible perovskite solar cells are promising for lightweight and versatile applications but their sensitivity to humidity and temperature poses a challenge to long-term durability. To address this, researchers have conducted a comprehensive study to test the degradation of these solar modules under extreme heat and humidity. Through accelerated testing, they identified how the water vapor transmission rates of barrier films affect the module's stability, giving critical insights for development of durable solar cells.
