Researchers from Northwestern Chemistry and Engineering have developed a method to improve the efficiency of hybrid perovskite solar cells (PSCs), bringing them closer to widespread use. The researchers used liquid crystals that can respond to temperature changes to protect large-area perovSKite films, resulting in a 22% efficiency and a stabilised efficiency of 21% for solar modules. This breakthrough could lead to more efficient and stable solar energy generation on a larger scale. The use of liquid crystals in this manner was a novel idea, as previous research had overlooked their ability to change with temperatures. The scientists believe this method can be extended to larger-area Perovskites sub modules and further exploration of liquid crystal molecules could enhance device stability.
