Solar cells are generally flat. However, by adding minuscule silicon pillars to the surface, it is possible to more than double the amount of energy produced for each surface. This has been demonstrated by research by academics at the University of Twente research institute MESA+. In an article published in the scientific journal Advanced Energy Materials, they show what the optimum height and doping depth of the pillars is.
