Opto-Electronics Review

In recent years, metal halide perovskites have gained significant attention due to their unique optical and electronic properties of semiconductor materials, which make them ideal for use in sustainable and energy-efficient devices. These devices include solar cells, lasers, and light-emitting diodes. Therefore, this review aims initially to provide an overview of the most important characteristics of metal halide perovskites, including their engineering development in various types, such as those based on lead or lead-free materials, like tin or germanium. Additionally, perovskites made from purely inorganic compounds like caesium bromide, chloride, or iodide, as well as hybrids mixed with organic compounds like formamidinium and methylammonium halides will be discussed. The goal is to improve their stability and efficiency. Secondly, some of the studies have proposed technologies combining electronic and mechanical characteristics of flexibility or rigidity as required, promoting their synthesis with different materials such as polymers (poly methyl methacrylate, polyvinylidene fluoride), biopolymers (starch, cyclodextrin, polylactic acid, and polylysines), among others. Finally, the subject of this work is to establish the main purpose of the research carried out so far, which is to develop simpler and more scalable processes at industrial level to achieve greater efficiency and duration in storage, exposure to visible light, critical environments, humid or high temperatures.
