Semitransparent perovskite solar cells are emerging as a promising technology for applications such as energy-generating windows and integrated photovoltaics, where a balance between efficiency, transparency, and aesthetics is essential. [1-5] Designing such devices demands a deep understanding of light absorption, reflection, and transmission within the cell structure. In this work, we outline a simulation-based methodology for optimizing these devices, beginning with the calculation of optical constants for each layer in the cell, which is key not only for understanding the limitations associated to different devices, but also for accurately predicting the best design for each application. [6-7] We show the importance of validating the accuracy of the optical model by comparing simulated results with experimental data of full devices, performing global fits of different devices which ensures the model reliability. Finally, we explore various optimization strategies aimed at achieving specific performance targets, such as maximizing power conversion efficiency while maintaining desired levels of transparency and color rendering properties. By integrating accurate material characterization, rigorous simulation validation, and strategic optimization, this approach accelerates the development of high-performance, semitransparent perovskite solar cells tailored for diverse applications. This framework offers a practical pathway for bridging the gap between fundamental research and scalable device design.
