Ensuring the long-term performance of dye-sensitized solar cells (DSSCs) and perovskite solar cells (PSCs) is paramount for their widespread adoption in the renewable energy landscape. While these next-generation photovoltaic technologies offer high efficiencies and low manufacturing costs, their susceptibility to degradation under various environmental and operational stresses remains a critical challenge.This book provides a comprehensive and in-depth exploration of the key factors that influence the stability of both DSSCs and PSCs. It meticulously examines the fundamental mechanisms behind material degradation, including the impact of moisture, oxygen, heat, light, and electrical bias. Expertly authored chapters delve into the specific vulnerabilities of each cell type, dissecting the degradation pathways of their constituent materials, such as dyes, electrolytes, metal oxides in DSSCs, and the organic-inorganic hybrid perovskite absorbers in PSCs.Furthermore, the book critically reviews the current state-of-the-art research and development efforts focused on enhancing the stability of these solar cells. It explores innovative strategies in material design, including the synthesis of more robust dyes and perovskite compositions, the development of stable charge transport layers, and the implementation of effective encapsulation techniques. Advanced device architectures and processing methodologies aimed at minimizing degradation are also thoroughly discussed.Beyond material and device-level solutions, the book addresses the crucial role of environmental factors and testing protocols in evaluating long-term stability. It highlights the importance of standardized testing procedures and provides insights into accelerated aging tests designed to predict the operational lifetime of solar cells under real-world conditions.This book serves as an indispensable resource for researchers, scientists, engineers, and students working in the fields of photovoltaics, materials science, chemistry, and renewable energy. It offers a holistic understanding of the stability challenges facing DSSCs and PSCs.
