    • Abstract


      Perovskite material is a great visible light absorber in perovskite solar cells (PSCs). PSC has reported power conversion efficiency (PCE) of 22.1%. However, performance instability of the solar device base on this material hampersits commercialization. One of the factors responsible for performance instability in the cell is temperature. In this work, we carried out stability study of perovskite film treated with tertiary butylpyridine (tBP) as a surface modifier. Concentrationsof tBP added in perovskite material film were varied and the samples were subjected to temperature degradation test in a temperature-controlled chamber for 120 h. Ultraviolet–visible (UV–Vis) spectrophotometers, Fourier-transform infrared (FT-IR) spectrometers andX-ray diffractometers (XRD) were used to characterize the properties of the temperature-stabilitytested samples. The results show that the sample treated with 100 $\mu$l of tBP has the best resistance to temperature degradation after the duration of the test. The surface-modified perovskite films, with 100 $\mu$l of tBP, may reduce the degradation of PSCs.
