Organic-inorganic metal halide perovskite materials offer wide range of positives such as lost cost materials, efficient photovoltaic cells, ease of fabrication and appears particularly promising for the next-generation solar cell devices. However, its comprehensive behavior in the reverse-bias is critical to understand the cell performance, stability and the abnormal hysteretic effects. In this study, we investigated on a contrasting study to understand the impact of reverse bias on different contacts such as Silver (Ag), Gold (Au), and Molybdenum Oxide with aluminum (MoO_X/Al). Furthermore, provide insights to the effects of hole transport layers such as spiro and EH44 (2,7-Di(N,N- dimethoxyphenylamino)-N-(2- ethylhexyl)carbazole) with ((FA_0.79MA_0.16Cs_0.05)_0.97Pb(I_0.84Br_0.16)_2.97) perovskite material. These findings further emphasize the versatility and performance potential of these perovskite materials for other optoelectronic applications.
