- Resumen
Given the need for sustainable energy alternatives and the environmental impact of fossil fuels, this thesis explores tin-based halide perovskites (Sn-HPs) as an eco-friendly option compared to the traditional lead-based perovskites materials in solar cells and LEDs. This thesis tackles the main challenges limiting Sn-HPs, such as instability and oxidation, through three innovative studies. First, the use of additives like DipI and NaBH¿ significantly improves solar cell efficiency and long-term stability. Second, inkjet printing technology is applied to create lead-free, flexible PeLEDs, demonstrating scalable and industrially relevant fabrication methods. Third, a low-cost synthesis of 2D and 3D Sn-HPs microcrystals using acetic acid enhances stability and performance in light-emitting devices, with emissions from orange to near-infrared. These advances contribute to more durable, efficient, and scalable Sn-HPs technologies, bringing us closer to greener solutions in renewable energy and optoelectronics.
