What if the same quirk that makes a solar cell degrade could also make it heal itself? Halide perovskites are an exceptional family of photovoltaic materials: cost-effective, highly efficient, and adaptable to flexible or semitransparent devices. But something that makes them truly unusual is that ions move freely within their structure, giving rise to fascinating physics that blurs the line between breakdown and recovery. This talk is an invitation to explore a fast-moving field where physics, materials science, and chemistry meet, and where understanding failure might be the key to building better, longer-lasting solar cells and unlocking new applications, from self-healing devices to neuromorphic electronics.
