Organometallic halide perovskite materials have triggered global attention in recent years due to their exciting and optimistic high performance energy conversion properties （high luminescence efficiency and tremendous optical absorption ability [1,2]）. These interesting photovoltaic properties together make them a promising candidate for high performance optoelectronic devices （Solar cells, Photodetectors, Image sensors and Light emitting diodes etc.） and switching from CdTe devices [3]. Despite of outstanding and stunning energy conversion abilities of organic perovskite materials, a big associated drawback with these materials is the poor stability and durability under ambient conditions. Organic perovskite is an ionic compound and destabilizes very quickly upon invasion of oxygen and water molecules [4-6]. A sequential decay process of perovskite material with oxygen and water diffusion has been explained below [7].
