A mini review of recent strategies towards stable nano-structure perovskite solar cell fabrication

Organic-inorganic perovskite solar cells (PSC) are drawing interest towards photovoltaic device fabrications due to low raw materials cost, easy room temperature fabrications, and exhibiting excellent tunable optoelectronic properties. Power conversion efficiency increased dramatically in the last few years despite challenges like instability in moisture and high ambient temperature conditions. However, techniques employed like encapsulation used to reduce perovskite degradation rate, long-term stability still an issue for commercial scale-up. Most of the perovskite materials, more precisely halide perovskites, are affected by the ambient humid conditions. In this present study, we explore the recent development of different strategies to fabricate moisture-resistant stable perovskite solar cell fabrication. This review discusses the structural influence on the stability of PSC.
