Reaching the Goldilocks Zone—Mastering the Defective Nature of Perovskite Solar Cells

While inherently “defect-tolerant,” metal-halide perovskite solar cells require precise control over growth and defect passivation to achieve peak efficiencies and enhanced operational stability in optoelectronic applications, the crux of maximizing performance is mitigating non-radiative defect-mediated recombination through the means of passivation. In this talk, I will present our perspective on how one could formulate a practical mitigation plan to tackle such a challenge that dictates most perovskite solar cells’ performance.
