September, LAKheswa, NSeroka, Ntalane SKhotseng, L2025-10-022025-10-022025-02978-1-83769-8837978-1-83769-885-1978-1-83769-884-4http://hdl.handle.net/10204/14427Perovskite materials have attracted attention because of their favorable features, which include configurable bandgap, improved charge transport, and unique electronic structure. The authors emphasize the most recent developments in PSC synthesis, innovative device architecture, bandgap engineering, charge transport processes, and stability. The need for a comprehensive design principle that surpasses the iterative process of the current synthesis of perovskite materials is highlighted. This is essential for developing high-quality, defect-free crystal structures with controlled dimensionality, and the choice of the deposition process is crucial to improve structural morphology in the production of PSC. This chapter also highlights that tandem and hybrid perovskite research is still in early development and emphasizes the need for basic research to fully understand the optical, electrical, and physical characteristics of the material before advances in industry.FulltextenPerovskite solar cellsTwo-step perovskite depositionBandgap engineeringOptoelectronic propertiesMaterial stabilityBook ChapterN/A
