Hybrid organic-inorganic halide perovskite material has been considered as a potential candidate for various optoelectronic applications. However, their high sensitivity to the environment hampers the actual application. Hence the technology replacing the organic part of the hybrid solar cells needs to be developed. Herein, we fabricated fullyinorganic carbon-based perovskite CsPbBr_3 solar cells via a sequential deposition method with a power conversion efficiency of 2.53% and long-time stability over 20 d under ambient air conditions without any encapsulation. An evolution process from tetragonal CsPb_2Br_5 to CsPb_2Br_5-CsPbBr_3 composites to quasi-cubic CsPbBr_3 was found, which was investigated by scanning electron microscopy, X-ray diffraction spectra, UV-vis absorption spectra and Fourier transform infrared spectroscopy. Detailed evolution process was studied to learn more information about the formation process before 10 min. Our results are helpful to the development of inorganic perovskite solar cells and the CsPb_2Br_5 based optoelectronic devices. |

有机无机杂化钙钛矿是一种有潜力的光伏材料. 然而, 对于环境的高度敏感性限制了它的实际应用. 因此我们需要发展全无机钙钛矿材料. 本文通过连续沉积法制备了效率达到2.53%的碳电极CsPbBr_3太阳电池, 并且它能够在无封装的情况下稳定20天. 在制备CsPbBr_3薄膜的过程中, 我们首次发现从CsPb_2Br_5到CsPb_2Br_5-CsPbBr_3混合物到CsPbBr_3的转变. 该研究结果对于无机钙钛矿太阳电池的发展和CsPb_2Br_5基光电器件具有帮助作用. |
