This thesis presents valuable findings on the synthesis and characterization of organic-inorganic bromide perovskites for solar cell applications. A key highlight is the discovery that using a polar solvent like dimethylformamide (DMF) leads to preferential growth of nanoclusters along the [h00] direction. This specific orientation is crucial for efficient charge carrier transport, making these materials promising for high-performance devices.
The detailed experimental methodology, utilizing techniques like FTIR, XRD, SEM, and XPS, provides a solid foundation for the conclusions. The identified chemical instability in samples from aqueous solutions also offers important insights for future synthesis optimization.
Overall, the thesis effectively communicates the significant impact of solvent choice on perovskite properties, underscoring the potential of DMF-synthesized perovskites for high-efficiency solar films.
