Abstract: Perovskite indoor photovoltaics (PIPVs) have emerged as a leading solution for low-light energy harvesting, owing to their exceptional optoelectronic properties, tunable bandgaps, and cost-effective fabrication. The nonlinear optical (NLO) properties of perovskite materials, including third-harmonic generation (THG) and two-photon absorption (TPA), offer an additional dimension for enhancing device performance under indoor illumination. This review explores recent advances in the field, with a focus on the interplay between stability, efficiency, and NLO effects. Computational approaches, such as Density Functional Theory (DFT) and nonlinear optical simulations, are examined to understand material behavior and predict device performance. The experimental breakthroughs in materials engineering, interface optimization, and the integration of NLO phenomena in device architectures are discussed. The review concludes by highlighting future opportunities and challenges in leveraging nonlinear properties for next-generation PIPVs. • Examines nonlinear optical (NLO) phenomena such as THG and TPA in the context of perovskite indoor photovoltaics (PIPVs). • Reviews computational insights from DFT and NLO simulations for predicting material behavior and device response. • Summarizes experimental progress in materials engineering, interface optimization, and NLO-enhanced architectures. • Identifies future challenges and opportunities in integrating NLO effects for stable, efficient, and scalable PIPVs.
