| 英文摘要 | The preparation of hybrid perovskite films with large columnar grains via low-temperature solid-state-reaction remains a big challenge. Conventional solvent annealing using DMF, DMSO and ethanol, etc. fails to work effectively at low temperature (<100 degrees C). Here, we comprehensively investigated the effects of non-coordinating solvent vapor on the properties of perovskite film, and obtained micron-sized columnar grains (with an average grain size of 1.4 mu m) of CH3NH3PbI3 even at a low temperature of 75 degrees C whenannealed with benzyl alcohol vapor. The perovskite solar cells based on benzyl-alcohol-vapor annealing (75 degrees C), delivered much higher photovoltaic performance, better stability and smaller hysteresis than those based on conventional thermal annealing. Additionally, a champion power conversion efficiency( PCE) of 15.1% was obtained and the average PCE reached 12.2% with a tiny deviation. Finally, the mechanism of solvent annealing with non-coordinating solvent was discussed. Moreover, we revealed that high polarity and high boiling point of the solvent used for generating vapor, was critical to grow micronsized columnar grains at such a low temperature (75.degrees C). This work will contribute to understanding the mechanism of grain growth in solvent annealing and improving its facility and effectiveness. (c) 2017 Published by Elsevier B.V. |
