Last year, we reported in an article how scientists discovered that the moth's eyes could increase the efficiency of solar cells. Thanks to the super-transparent coatings, windows in homes and cars, computer screens and other consumer products could be improved. Now, new figures show the advances in this nature-mimicking technology.

Even though plastic solar cells are cheaper to produce and they have some advantages like lightweight and flexibility , they still miss one important thing: the efficiency. Researchers are optimist that in the years to come, the polymer solar cells will be able to compete from the efficiency point of view with the silicon solar cells as well taking into account the fact that plastic solar cell have improved their efficiency each year.
