Outstanding performance of organic solar cell using tin oxide

Organic solar cells have a photoactive layer that is made from polymers and small molecules. The cells are very thin, can be flexible, and are easy to make. However, the efficiency of these cells is still much below that ...

Enhancing organic solar cells' green glow

Organic solar cells could be made even greener by switching the solvents used in their manufacture. Today's toxic chlorinated solvents can be replaced by plant-derived alternatives without affecting the resulting solar cells' ...

Marrying models with experiments to build more efficient solar cells

In a single day, enough sunlight strikes Earth to power the world for an entire year—that is, if we can find a way to capture that energy cheaply and efficiently. While the cost of solar energy has decreased dramatically, ...
