Metal-halide perovskites remain one of the most discussed and promising materials for optoelectronic applications. Tunable optoelectrical properties of the materials have inherent qualities that find applications in both military and civilian purposes. One of the main applications for the materials is large-scale low-cost solar energy generation. Perovskite Solar Cells (PSCs) have continuously demonstrated Power Conversion Efficiencies (PCEs) above 24%, cost reductions above 30%, direct band-gap structures, and low-temperature malleability for utility-scale applications. Industry is actively exploring potential applications for the perovskite materials and pursuing efforts to leverage these materials in CO2 footprint reduction. Current challenges of the materials lie in the acquisition of high-quality stable, and ruggedized films with lifetimes above 5 years. Encapsulation can provide stability from film oxidation, but hydrophilicity, thermal and light stability of the materials remain to be solved. This work demonstrates progress in obtaining metal-halide perovskite stabilities and describes the possibility of integrating these materials for a broad range of uses.
