This study reports direct-current droplet energy harvester based on a thin composite film utilizing CYTOP/BaTiO3 nanoparticles. To overcome the limitations of conventional hydropower and effectively utilize small water supplies such as raindrops, a new type of droplet energy harvester was developed that promotes instantaneous charge transfer through the innovation of surface electrode structures and the use of ferroelectric nanoparticles. In this device, a CYTOP® solution mixed with BaTiO3 nanoparticles of varying concentrations is coated on an ITO thin film on a glass substrate to form a composite film. This method has improved the output voltage from 160 V to 900 V and enabled the charge transfer amount to exceed 100 nC. As a result, a higher energy generation efficiency than before has been achieved. This research represents a significant advancement in the field of environmental energy harvesting.
