Operation Mechanisms and Scalable Manufacturing Methods for Perovskite Solar Cells: A Review

Abstract

This review explores the working principles and manufacturing techniques of perovskite solar cells (PSCs), a fast-growing and highly promising area in solar energy research. In recent years, PSCs have attracted considerable attention because of their high efficiency, affordable fabrication, and use of versatile materials. What makes them stand out is their ability to convert sunlight into electricity efficiently using lightweight, low-cost, and flexible materials, which are easier and cheaper to process than traditional silicon-based cells. With the increasing global demand for clean and renewable energy, PSCs offer a pathway to affordable and scalable solar power. Studies have shown that using methylammonium lead iodide (CH₃NH₃PbI₃) a commonly used perovskite material along with a smart device design, can result in energy conversion efficiencies up to 3.81%, supported by high incident photon-to-current efficiency (IPCE) and short-circuit current density (Jsc). Further improvements were achieved using zinc oxide (ZnO) films with a 440 nm thickness, which showed 10.8% efficiency thanks to their porous structure and excellent electron transport properties. Additionally, three-dimensional nanocomposites combining mesoporous titanium dioxide (TiO₂) with CH₃NH₃PbI₃ were found to enhance performance significantly. Doping TiO₂ with nickel further improved the system by raising the Fermi level and boosting charge mobility in the electron transport layer, allowing better movement of electric charges within the device. Moreover, PSCs are compatible with a range of fabrication methods, including spin coating, inkjet printing, and roll-to-roll processing, which are cost-effective and suitable for large-scale production. This flexibility in manufacturing opens the door for applications such as flexible solar panels, solar fabrics, building-integrated solar modules, and portable energy solutions. In summary, the ongoing devewelopment of new materials and structures, combined with innovations in scalable manufacturing, continues to improve the performance, stability, and commercial potential of perovskite solar cells making them one of the most exciting technologies for the future of clean energy.
