Organic Solar Cell Breakthrough Improves Performance And Stability

Gwangju Institute of Science and Technology (GIST) scientists use a water treatment for morphology control in the fabrication of active layer thin films, improving the performance and stability of large-area organic solar cells. Morphology control is essentially about making and placing very small particles in their working position. Albeit somewhat a simplified description, as miniaturization becomes micro miniaturization and now molecule, crystal and sometimes even atom placement, the process engineering efforts are getting very challenging indeed.…
