Biomimetic Vascular Solar Cells

October 9, 2013 · Print This Article

Researchers at North Carolina State University have come up with a new way of making solar cells with a method that uses circulation much like that in plant leaves to maintain the efficiency of the cells.

Dye-sensitized solar cells (DSSC) are organic cells that use light-sensitive dyes to generate electricity. These cells could eventually invent low-cost and more environmentally-friendly collectors for solar energy, but until now, the problem has been that the dyes eventually

break down due to ultraviolet rays from the sun and lose their efficiency.

The NCSU scientists have created a cell with vascular chanels, much like the veins in a leaf, to allow them to replenish the dye and thereby maintain the efficiency of the cell. Lead author Prof. Orlin Velev describes the process: “We considered how the branched network in a leaf maintains water and nutrient levels all through the […]
