Full(erene) potential: Adding specific molecules to `trap` charge carriers in semiconducting polymers
(PHYSorg.com Chemistry)

In what could be called a classic `Eureka` moment, UC Santa Barbara materials researchers have discovered a simple yet effective method for mastering the electrical properties of polymer semiconductors. The elegant technique allows for the efficient design and manufacture of organic circuitry (the type found in flexible displays and solar cells, for instance) of varying complexity while using the same semiconductor material throughout.
