ABSTRACT

Wood-based solar nano-evaporation power generation devices have attracted widespread research interest due to their renewable and green characteristics. However, current research on wood-based solar nano-evaporation power generation devices mostly focuses on surface changes. Here, we conducted a study on the effect of the contact area between the underwater part of a wood-based solar nano-evaporation power generation device and water on the evaporation and power generation performance. By changing the contact surface between FDEW and water, an ultra-high evaporation rate of up to 4.17 kg m-2 h-1 can be achieved under 1 sun irradiation. Furthermore, through COMSOL Multiphysics simulation, it was verified that reducing the underwater area can significantly increase the output potential of the nano-power generation device. Our work provides a new idea for nano-evaporation power generation devices and expands the application path of designing high-performance nano-evaporation power generation devices in power-related fields.
