This book is designed to provide detailed reviews of the progress of perovskite solar cells using conjugated polymers, with a focus on enhancing the performance of hybrid devices. The reader will understand the working principles of perovskite solar cells, the characteristics of conjugated polymers as HTMs (such as P3HT), the nature of hole transport materials, and also learn about advancements in perovskite solar cells aimed at improving device performance and charge stability through the impact of conjugated polymers like HTM-[P3HT], summarized along with future outlooks.
I would like to express my gratitude to my supervisor, Dr. Chernet Amente, from the Faculty of Computational and Natural Science Department of Physics at Addis Ababa University. He provided invaluable guidance throughout my research and offered insightful feedback on my writing, helping me refine my work. Dr. Amente has been an excellent sounding board, significantly shaping my approach to scientific thinking. I also want to extend my thanks to Dr. Newaymedehn Abera, a researcher in the Physics Department at Addis Ababa University. I am grateful for his patience in teaching me the experimental and numerical approach.
I dedicate this chapter to the memory of my father, ‘YESIGAT WALELGN HUNEGNAW,’ who has recently passed away. Losing him feels like losing my greatest blessing and source of comfort, as he was always that to me. Additionally, I want to express my gratitude to my family, including my children, for motivating me to give my best effort in everything I pursue.
