Application of wooden arrays in solar water evaporation and desalination
Source abstract
Abstract
Abstract Interfacial evaporation is one of the most promising technologies for harvesting solar energy to generate steam. Here, we report a solar interfacial evaporator with excellent self-cleaning property via a well-designed artificial channel array in the raw wood substrate. This device shows high light absorption nearly 90% and high solar-to-vapor conversion efficiency of ~88.2% of pure water under one sun irradiation. In addition, due to the existence of two different channels on the device surface: man-made millimetre-sized cutting channels and micro-channels formed by natural growth, the deposition of salt was reduced and its long-term stability in the NaCl solution (over 80 h of continuous operation) was increased. Based on the above conditions, the PCW-7 × 7 still maintains its efficiency at about 80.0% and 73.4% at 1 kW m-2 irradiation in the different simulated seawater with different salinities (3.5 and 20 wt%).
