From Chemistry to Solar Cells: The Central Role of Materials Innovation in Perovskite Photovoltaic Revolution

ABSTRACT Perovskite solar cells (PSCs) have emerged as transformative technology in the field of photovoltaics. Following their inception in year 2009, they have become within a decade the leading candidate for next‐generation photovoltaics due to their exceptional efficiency, low‐cost processing, and tunable optoelectronic properties. However, challenges surrounding long‐term stability, lead toxicity, and industrial scalability remain major barriers to large‐scale commercialization. This perspective explores the central role of materials innovation in overcoming these obstacles, focusing on advances in compositional engineering, molecular additives and passivation, interfacial chemistry, and 2D/quasi‐2D perovskite systems. Particular attention is given to the evolution of charge transport architectures and the emerging commercial landscape. We also highlight the importance of shifting from performance‐driven research to durability‐ and manufacturability‐conscious strategies. The article concludes with recommendations for future directions in PSC development, including the need for standardized testing, predictive materials design, and environmentally responsible fabrication.
