Opis:
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.

Opis:
Perovskite cells are a new generation of solar cells that have gained significant attention in the field of photovoltaics due to their unique properties and potential benefits. Perovskites are a class of materials that have a characteristic crystal structure known as the perovskite structure. The typical chemical formula of perovskite is ABX3, where 'A' and 'B' are cations that differ in size, and 'X' is an anion, most often halogen. Doping with alkali metals in perovskite materials has shown a significant improvement in the efficiency of the solar cell, which is confirmed by numerous scientific studies. The addition of rubidium bromide and other alkali metals, such as lithium, sodium and potassium, affects the microstructure, electronic and optical properties of perovskites, which is crucial for the efficiency and stability of solar cells. The paper presents research results on doping with alkali metals for inorganic perovskite cells based on CsPbBr3. The process of doping with alkali metals was carried out in various stages of creating a Perovskite cell. The work presents the influence of the dopant on the structure of the perovskite and the obtained cell, as well as its optical and electrical properties. The conducted research indicates a positive effect of the addition of rubidium bromide, both in the phase of creating the lead bromide layer and during the application of cesium bromide. The most promising is the admixture of 9% rubidium bromide in the cesium bromide layer. In this way, the applied dopant is located in the perovskite structure, changing its optical and electrical properties.
