Modeling and TCOs Engineering for Thin-Film Photovoltaic Technologies

This dissertation investigates bilayer and indium-free transparent conductive oxides, establishing processing–property relationships governing conductivity, transparency, and interface morphology in superstrate thin-film photovoltaic architectures. These experimentally optimized materials are integrated into a predictive optoelectrical modeling framework validated against thin-film silicon devices fabricated on glass and flexible aluminum foil substrates. The framework is subsequently extended to flexible perovskite single-junction and tandem architectures, with particular focus on the design of the hole transport layer. Overall, this work demonstrates how physically grounded modeling and superstrate thin-film platforms can support the development of scalable, high efficiency, and mechanically flexible photovoltaic technologies.
