A researcher who coauthored a method for increasing the <exciton diffusion length> in <organic solar cells>. Diluting the absorbing donor molecules in a material with a wider <band gap> changed their interactions and increased the distance an <exciton> could travel. This helps excitations reach the charge-separating interface before they decay, improving useful collection of absorbed <light>.<Tailored exciton diffusion in organic photovoltaic cells by S. Matthew Menke and others>[Abstract: donor dilution, approximately 50 percent diffusion-length increase and improved efficiency]{ref}
