Such systems are anticipated to exhibit high efficiency, robust durability, consistent power output, and the potential for effortless integration. Integrating ultraflexible energy harvesters and energy storage devices to form an autonomous, efficient, and mechanically compliant power system remains a significant challenge.
For the energy harvesting component, we have boosted the PCE of ultraflexible OPVs up to 16.18%. The freestanding OPVs demonstrate exceptional long-term storage stability that extends beyond two months, and operational stability for over 500 h under continuous illumination. We also scaled up the devices into solar modules.
A monolithically integrated photo-rechargeable power source was developed using Si photovoltaics and Li-ion batteries 18. A bipolar stacked solid-state battery configuration was used, resulting in an overall voltage output of 5.4 V from the battery module.
Our ultraflexible OPV module can efficiently produce power in various lighting conditions, even with dim or indoor illumination. For instance, under an overcast sky that yields an average light intensity of approximately 7000 lux, the 6.72 cm 2 module generates a power output of 3.5 mW (Fig. 3E).
