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.
