This work presents a novel solar energy harvesting fabric that can power wearable and mobile electronic devices in a robust, user-friendly, and sustainable manner. The fabric was realised by weaving miniature solar cell embedded textile yarns (solar-E-yarns) fabricated using the Electronic yarn (E-yarn) technology. The fabric (44.5 mm × 45.5 mm active area) can generate a maximum power density of 2.15mW/cm2 under one sun (1000 W/m2) solar illumination and looks and feels like a normal textile; it is soft, three dimensionally conformable, breathable and moisture absorbing. It is also capable of undergoing machine laundering, which has not previously been reported by a textile solar energy harvesting solution for wearable applications in the literature. The fabric can be rolled and is lightweight, making it desirable for mobile and off-the-grid energy needs.
