Photovoltaic Device design and Development for Performance Enhancement: Semiconductor Solar cell vol II

This book deliberates a comprehensive understanding into the design, modelling, and performance enhancement of next-generation photovoltaic devices. The book systematically optimizes antireflection layer materials and thicknesses, demonstrating that ZnO material achieves a superior power conversion efficiency in contrast to other existing options due to its exceptional refractive index matching and thermal stability. A novel electron transport layer architecture employing Sn-doped TiO¿-coated ZnO nanorods is developed, yielding significant efficiency improvements to around 30% while employing perovskite solar cells. The work further provides a comparative analysis of graphene-based Schottky junction solar cells on GaAs and silicon substrates, achieving enhanced efficiencies under AM1.5G illumination. Additionally, the design of high-efficiency PERC cells utilizing SiO¿, Si¿N¿, and Al¿O¿ passivation layers are also explored which attains a fill factor of 80.71% and efficiency of 23.82%. Collectively, this research offers valuable design guidelines and optimization strategies for developing cost-effective, high-performance solar cells for terrestrial applications.
