Novel routes and insights into halide perovskite solar cells
This thesis investigates halide perovskite solar cells as a sustainable and efficient alternative to silicon-based solar cells. The study employs electron backscatter diffraction (EBSD) to examine perovskite films, revealing it as a powerful tool for correlating crystallographic information with thin-film properties. A novel contact transfer method is introduced for creating highly oriented perovskite crystals with the assist of self-assembled nanocube layers, compatible with various perovskite compositions and offering potential industrial applications. Back contact perovskite solar cells are studied, identifying loss mechanisms, and suggesting improvements to achieve higher efficiency. Suitable passivation materials are assessed, with SiO2 emerging as an effective option, enhancing device performance when applied to back contact perovskite solar cells . This comprehensive investigation contributes to the growing research on perovskite solar cells , emphasizing their potential in addressing global energy demands. The development of high-efficiency, low-cost, and sustainable solar energy solutions can be accelerated by refining the techniques and materials discussed, ultimately leading to a cleaner and more secure global energy landscape.
