The commercial use of perovskite solar cells is inhibited by their poor stability. Incorporating ionic liquids into perovskites helps to overcome this challenge, enabling the development of solar cells with 25.9% efficiency that retain 90% of their initial performance for over 1,500 hours under continuous 1-sun illumination and temperatures of 90°C.
