摘要/Abstract

摘要： 半铅锡钙钛矿太阳能电池因其窄带隙低毒性的优点，成为了钙钛矿太阳能电池研究中的热点方向。但是铅锡钙钛矿成膜质量差，限制了电池效率的提高。通过在前驱液中加入二甲基亚砜延缓薄膜结晶速率，制备了致密无孔洞的高质量薄膜。同时，使用氟化锡和富勒烯衍生物分别减少了钙钛矿晶格中和晶界、界面处的缺陷,提高了器件效率。通过上述手段制备的半铅锡钙钛矿太阳能电池效率可达15.1%。

Abstract: Due to its narrow band gap and low toxicity, the lead-tin perovskite material is widely used in fabricating perovskite solar cells. However, the efficiency of lead-tin perovskite is low, because of its poor film quality. In order to improve the film quality, we added dimethyl sulfoxide into the precursor solution to decrease the crystallization speed and fabricated a dense pinhole-free perovskite film. Moreover, tin fluoride and fullerene derivatives were added to reduce defects in the perovskite lattice and grain boundaries and surface. An efficiency up to 15.1% was recorded by the above methods.

Key words: solar cell, lead-tin perovskite, improve morphology, passivate defect
