First ever high-res 3D images of polymer solar cells obtained
Polymer solar cells may be far from being the Silicon Valley entrants for everything just about yet. Because they have the ability to be printed in a roll-to-roll process, we’d definitely want to see them up there for their efficiency and the advantageous nature at the earliest. To get the polymer solar cells deliver in the highest grades, we need to understand nanoscale structure of these polymers thoroughly, in event thus scientists at the Eindhoven University of Technology and the University of Ulm have managed high-resolution, 3D images of the inside of a polymer solar cell.
In this, first of its kind experiment, dubbed “The effect of three-dimensional morphology on the efficiency of hybrid polymer solar cells,” ‘3D electron tomography was used to demonstrate the importance of the degree of mixing in determining the absorbed photon rates in the polymPer solar cells,’ wherefrom the scientists obtained a 50-percent absorption rate.
