AbstractHybrid energy-harvesting systems that capture both wave and solar energy from the oceans using triboelectric nanogenerators and photovoltaic cells are promising renewable energy solutions. However, ubiquitous shadows cast from moving objects in these systems are undesirable as they degrade the performance of the photovoltaic cells. Here we report a shadow-tribo-effect nanogenerator that hybrids tribo-effect and shadow-effect together to overcome this issue. Several fiber-supercapacitors are integrated with the shadow-tribo-effect nanogenerator to form a self-charging power system. To capture and store wave/solar energy from oceans, an energy ball based on the self-charging power system is demonstrated. By harnessing the shadow-effect, i.e. the shadow of the moving object in the energy ball, the charging time shortens to 253.3 s to charge the fiber-supercapacitors to the same voltage (0.3 V) as using pure tribo-effect. This cost-effective method to harvest and store the wave/solar energy from the oceans in this work is expected to inspire next-generation large-scale blue energy harvesting.

This work presents an innovative solar energy harvesting fabric and demonstrates its suitability for powering wearable and mobile devices. A large solar energy harvesting fabric containing 200 miniature solar cells has been shown to charge a 110 mF textile supercapacitor bank within 37 s. A series of solar energy harvesting fabrics with different design features, such as using red or black fibres, were tested and compared to a commercially available flexible solar panel outside under direct sunlight. The results showed that the solar energy harvesting fabrics had power densities that were favorable when compared to the commercially available solar cell.
