Solar-driven interfacial
evaporation,
as one of the most effective ways to convert and utilize solar energy,
has attracted lot of interest recently. Most of the previous research
studies, however, mainly focused on nonpatterned solar absorbers by
improving the structural and chemical characteristics of the solar
absorbers used in the interfacial evaporation systems. In this work,
we investigated the influence of patterned surface on the evaporation
performance of solar absorbers. The patterned surfaces studied, which
include black patterns and white patterns, were achieved by selectively
printing carbon black on the air-laid paper. Such a design leads to
the lateral temperature differences between adjacent patterns of the
solar absorber under solar illumination. The temperature differences
result in the lateral heat and mass transfer between those patterns,
which can effectively accelerate solar-driven vapor generation. With
similar patterns and same coverage of carbon black, the increase in
the circumference of the surface patterns leads to the increase in
the evaporation performance. Additionally, we found that the evaporation
performance can be optimized through the design of surface patterns,
which demonstrates the potential in reducing the usage of the light-absorbing
materials in the solar absorber. The findings in this work not only
expand the understanding of the interfacial evaporation systems but
also offer additional guidelines in designing interfacial evaporation
systems.
