Special Issue Information

Dear Colleagues,

The world desperately needs green energy sources. Perovskite solar cells are efficient and cheap to produce, making them attractive for researchers and many start-up companies. However, due to the doubly lower ionicity of halide perovskites compared with that of their oxide cousins, the stability of the former is poor. Material degradation processes under exposure to light, moisture, temperature, and device operation conditions such as current and voltage must be controlled to obtain long-lived and stable devices.

To date, our knowledge of degradation mechanisms includes an evolution of defects, grain boundary, surfaces, and interfaces with charge transporting layers. Nevertheless, more work is required in this field to achieve the goal. Further intensive and comprehensive studies on perovskite materials and device properties under harsh conditions are crucial for future development.

The aim of this Special Issue of Materials is to attract reports on the most recent achievements of device technology for stable and durable operation. We also invite works devoted to basic experimental research on processes in these compounds and theoretical modeling designed to achieve a deep understanding of degradation mechanisms and ideas to prevent degradation.

Halide perovskites are widely used as components of electronic and optoelectronic devices such as solar cells, light-emitting diodes (LEDs), optically pumped lasers, field-effect transistors, photodetectors, and γ-detectors. Despite this wide range of applications, the construction of an electrically pumped perovskite laser remains challenging. In this paper, we numerically justify that mixing two perovskite compounds with different halide elements can lead to optical properties suitable for electrical pumping. As a reference, the chosen model material was CsPbBr3, whose performance as a part of lasers has been widely recognised, with some Br atoms substituted by I at specific sites. In particular, a strong enhancement of the low-energy absorption peaks has been obtained using the ab initio Bethe–Salpeter equation. Based on these results, we propose specific architectures of ordered doping that could be realised by epitaxial growth. Efficient light emission from the bottom of the conduction band is expected.

The exact control of material properties essential for solar applications has been made possible because of perovskites’ compositional engineering. However, tackling efficiency, stability, and toxicity at the same time is still a difficulty. Mixed lead-free and inorganic perovskites have lately shown promise in addressing these problems, but their composition space is vast, making it challenging to find good candidates even with high-throughput approaches. We investigated two groups of halide perovskite compound data with the ABX3 formula to investigate the formation energy data for 81 compounds. The structural stability was analyzed over 63 compounds. For these perovskites, we used new library data extracted from a calculation using generalized-gradient approximation within the Perdew–Burke–Ernzerhof (PBE) functional established on density functional theory. As a second step, we built machine learning models, based on a kernel-based naive Bayes algorithm that anticipate a variety of target characteristics, including the mixing enthalpy, different octahedral distortions, and band gap calculations. In addition to laying the groundwork for observing new perovskites that go beyond currently available technical uses, this work creates a framework for finding and optimizing perovskites in a photovoltaic application.
