A research team, headed by Professor Liang Chao from the School of Physics at Xi'an Jiaotong University and in collaboration with Professor Zhang Jinbao's group from Xiamen University, has put forward an innovative solid-state molecular press annealing (MPA) approach. This approach aims to boost both the efficiency and long-term stability of perovskite solar cells. Traditional thermal annealing methods often trigger crystal defects, such as iodine vacancies, which subsequently lead to a decline in cell performance. The MPA strategy entails imprinting a pyridyl molecular template onto the perovskite film's surface during the annealing process. This technique, without relying on extra solvents, can effectively curb defect formation at the molecular level, stabilize the lead-iodine bond network, and hinder the creation and spread of iodine vacancy defects. Experimental results reveal that perovskite solar cells crafted using the MPA strategy attain a peak photoelectric conversion efficiency of 26.6% for small-area cells measuring 0.08 cm², nearly 25% for large-area cells of 1 cm², and 23% for large-area module devices spanning 16 cm². Furthermore, these cells demonstrate outstanding stability, retaining over 98% of their initial efficiency after operating continuously for over 1,600 hours at 85°C and 60% relative humidity, and exhibiting virtually no performance decline after being stored in the environment for more than 5,000 hours.
