Advancing beyond the limits of traditional silicon devices, this study explores material and interface innovations that enable high-efficiency and durable next-generation solar and sensing devices. We first demonstrate flexible and transparent crystalline silicon solar cells through nanophotonic design and doping-free, field-induced junctions based on atomic layer deposition (ALD), achieving record efficiencies while maintaining optical transparency. Extending this approach to perovskite photovoltaics, interface ligand engineering allows uniform and damage-free ALD oxide deposition, leading to highly stable perovskite-based tandem cells exceeding 27% efficiency and projected long-term reliability over 10 years. Furthermore, we introduce a novel silicon-based, field-induced UV-selective photodiode for early fire detection. These results collectively outline a materials-to-systems roadmap toward high-performance, durable optoelectronic technologies for solar and sensing applications.
