摘要

The structural, optical and excitonic characteristics of MA_xCs_1-xPb(I_xBr_1-x)₃ crystal thin films were investigated by using the X-ray diffraction patterns, scanning electron microscopic images, absorbance spectra and photoluminescence (PL) spectra. The time-dependent PL spectra shows that the MA_0.8Cs_0.2Pb(I_0.8Br_0.2)₃ crystal thin film is a photo-stable light absorbing material, which results in an efficient and stable perovskite solar cell without the additional encapsulation. The highest power conversion efficiency (PCE) of MA_0.8Cs_0.2Pb(I_0.8Br_0.2)₃ solar cells is 10.02%. In addition, the PCE decreases slowly toward a stable value (5.71%) for more than 120 days under moderate environment conditions (55–60 RH%).
