In recent years, the development of weightless, ultrathin, and non-toxic devices has received tremendous interest owing to their potential applications as building blocks for various flexible, wearable, and skin mountable systems. In this view, we explored the exceptional performances of flexible energy harvesters and storage devices along with wearable optoelectronic devices by adopting high-quality graphene monolayers and a user-friendly transfer methodology. Flexible and transparent energy generators with an active layer (AL) thickness of-20 mm and storage devices (AL
