A collaborative research team, co-led by Professor Liang Chao of Xi'an Jiaotong University and Professor Zhang Jinbao of Xiamen University, has introduced an innovative solid-state molecular imprinting annealing technique. This approach sheds new light on bolstering the durability of perovskite solar cells. Throughout the thermal annealing procedure, the technique entails the in-situ imprinting of pyridyl molecular templates onto the perovskite surface. This action effectively curbs the creation and spread of iodine vacancies, while simultaneously preventing thermally induced structural deterioration at its origin. Perovskite solar cells crafted through this method have attained an efficiency rate of 26.6% in small-scale devices and sustained an efficiency of 23.0% in large-scale modules, showcasing remarkable longevity. The pertinent discoveries were published online in the esteemed journal Science on January 9.
