About 25% of a solar panel’s costs arise from the material costs of the silicon used, which is an expensive material. By applying a smart technology it is possible to produce a solar cell that is equally efficient. Solar cells can be made cheaper by making them thinner. Within a NanoNextNL project Frank Lenzmann (ECN) investigated together with AMOLF whether photonic nanostructures could ensure that a solar cell captured the same amount of light with thinner layers of the expensive material silicon. Read more about the investigation and the application of these cheaper and thinner solar cells in the highlight Cheaper solar cells due to nanotechnology.
