Photovoltaics play a crucial role in the transition to renewable energy. However, conventional rigid and bulky solar cells fail to meet the demands of emerging applications, where mechanical compliance and high specific power are essential.

Recent advancements in perovskite solar cells demonstrate significant potential for seamlessly integrating solar power into diverse applications, such as wearables, biomedical, and aerospace systems, transforming how we interact with technology and utilize energy in daily life.

This presentation will explore the potential of small-scale, thin, lightweight, and flexible perovskite solar cells in advancing next-generation electronics. Through meticulous precursor solution engineering, diligent optimization of device interfaces, and careful substrate selection, we have significantly enhanced the performance and stability of lightweight photovoltaic cells. These advancements have also enabled their integration into complex systems that would otherwise be challenging for traditional photovoltaic technologies.

Case studies—including a solar-powered wearable metabolic analysis platform [1] and a lightweight quadcopter drone [2]—highlight the transformative potential of small scale lightweight perovskite photovoltaics by enabling innovative applications and reshaping our relationship with technology and energy consumption.
