Molecular additives enhance mechanical properties of organic solar cell material

Ganesh Balasubramanian, P.C. Rossin assistant professor of Mechanical Engineering & Mechanics at Lehigh University, and his graduate student Joydeep Munshi demonstrated that adding small molecules to a semiconducting polymer blend enhances the performance and stability of material used in organic solar cells. The study is described in an article, 'Elasto-morphology of P3HT:PCBM bulk heterojunction organic solar cells' featured on the back cover of Soft Matter.
