Design and Synthesis of New Carbazole based Hole Transporting Materials for Perovskite Solar Cells

Abstract

This thesis focuses on the design and synthesis of carbazole-based derivatives as p-type materials for PSCs. The primary objective is to enhance the long-term stability of PSC devices, a key limitation for commercialization, while simultaneously improving their photovoltaic performance. Historically, molecular design for PSC applications often proceeded without a detailed understanding of the materials properties, which might lead to suboptimal performance. In contrast, this study adopts a more strategic approach by leveraging computational tools like Gaussian 09 and Gauss View 16 to design molecules with tailored molecular properties to meet specific criteria for PSC applications. The designed carbazole derivatives were carefully selected based on their ability not to interfere with the light absorption of the perovskite layer. newline
