电子回流阻挡层提升钙钛矿太阳能电池的光电性能
Electronic Reflux Barrier Layer for Improving Photoelectric Performance of Perovskite Solar Cells
摘要
Abstract
Using the spin-coating method,1-amantadine hydrochloride(ADA)was introduced as an interface modifier between tin dioxide(SnO2)and perovskite layers to form an electron reflow barrier layer,which served to passivate interface defects,prevent electron reflow,and suppress non-radiative recombination at the interface,and could also enhance the photoelectric performance of perovskite solar cells.The results showed that the amino lone pair electrons in ADA could coordinate with uncoordinated Pb2+,which was conducive to the formation of high-quality perovskite films,reducing defect density and increasing open-circuit voltage.The optimal power conversion efficiency(PCE)of the perovskite solar cells modified by ADA reached 23.07%,the open-circuit voltage was 1.13 V,the short-circuit current density was 24.67 mA·cm-2,and the fill factor was 82.59%.After being stored in an air environment for 1 000 h,the modified device still maintained a PCE of over 85%,and both efficiency and stability were significantly enhanced.关键词
