I. INTRODUCTION The relentless pursuit of sustainable energy generation has become a defining endeavor of our time, driven by the urgent need to address climate change, environmental preservation, and the depletion of finite fossil fuel resources. The transition to renewable energy sources is not just an environmental imperative but a multifaceted challenge that intertwines with economic growth, energy security, and societal well-being. Among the suite of renewable technologies, photovoltaics (PV) have carved out a pivotal role due to their unique ability to convert sunlight directly into electricity, offering a clean, versatile, and scalable solution to global energy demands. Photovoltaic technology has become synonymous with the modern renewable energy movement, standing out for its direct harnessing of the sun's abundant energy. The adaptability of PV systems allows for a wide range of applications, from small-scale residential installations to vast solar farms, making solar energy a cornerstone in the quest for a decarbonized energy grid. As the world grapples with the pressing need to reduce greenhouse gas emissions, photovoltaics offer a pathway to not only meet climate targets but also to revolutionize the energy landscape with a sustainable and inexhaustible energy supply. The historical journey of photovoltaic materials is a narrative of scientific breakthroughs and technological milestones. From the early discovery of the photovoltaic effect to the development of the first silicon solar cell, the field of photovoltaics has been marked by a continuous search for improved materials and efficiencies. The evolution from bulky, expensive first-generation silicon wafers to the latest thin-film and organic photovoltaic materials reflects the dynamic nature of PV research and development. Each advancement brings us closer to a future where solar energy is not only ubiquitous but also integral to meeting the world's energy needs sustainably. 28
