Schematic of the cross section of a solar thermal membrane distillation device under focused illumination. Saline feed and purified distillate flow are on the top and bottom, respectively, of a carbon black-coated PVDF membrane in a countercurrent configuration. The illuminated area is covered with a lens array to concentrate the incident light on the coated membrane surface.
