Highly efficient flexible perovskite solar cells with vacuum-assisted low-temperature annealed SnO2 electron transport layer
文献摘要：
The demand for lightweight,flexible,and high-performance portable power sources urgently requires high-efficiency and stable flexible solar cells.In the case of perovskite solar cells(PSCs),most of the com-mon electron transport layer(ETL)needs to be annealed for improving the optoelectronic properties,while conventional flexible substrates could barely stand the high temperature.Herein,a vacuum-assisted annealing SnO2 ETL at low temperature(100℃)is utilized in flexible PSCs and achieved high effi-ciency of 20.14％.Meanwhile,the open-circuit voltage(Voc)increases from 1.07 V to 1.14 V.The flexible PSCs also show robust bending stability with 86.8％of the initial efficiency is retained after 1000 bending cycles at a bending radius of 5 mm.X-ray photoelectron spectroscopy(XPS),atomic force microscopy(AFM),and contact angle measurements show that the density of oxygen vacancies,the surface rough-ness of the SnO2 layer,and film hydrophobicity are significantly increased,respectively.These improve-ments could be due to the oxygen-deficient environment in a vacuum chamber,and the rapid evaporation of solvents.The proposed vacuum-assisted low-temperature annealing method not only improves the efficiency of flexible PSCs but is also compatible and promising in the large-scale commer-cialization of flexible PSCs.
