"solar electronics that are flexible, powerful, and better for the environment... organic compound that separates positive and negative components that are essential to solar cells into separate stacks.We took one set of molecules, or pancakes if you will, and bent them using organic chemistry so they don't stack well with the other type... change in shape made it much easier to have two organized stacks for better electrical flow... synchrotron was key in determining the structure of our compound"
