The efficiency of solar cells depends on precise engineering of polymers that assemble into films 1,000 times thinner than a human hair. Today, formation of that polymer assembly requires solvents that can harm the environment, but scientists have found a ‘greener’ way to control the assembly of photovoltaic polymers in water using a surfactant — a detergent-like molecule — as a template.
