Serious shortcomings in aging tests of new solar cell materials

Researchers at Aalto University have found that only a fraction of stability tests done on new types of solar cells meet proper requirements. Tests lack common standards and should have been done in real-world conditions ...

Nanostructure boosts stability of organic thin-film transistors

A nanostructured gate dielectric may have addressed the most significant obstacle to expanding the use of organic semiconductors for thin-film transistors. The structure, composed of a fluoropolymer layer followed by a nanolaminate ...

New method benchmarks organic mixed conductors

Within the past five years, Northwestern University's Jonathan Rivnay has noticed a surge in the development of new organic mixed conductors—polymer materials that can transport both electrons and ions. Lighter, more flexible, ...

A curious quirk brings organic diode lasers one step closer

Since their invention in 1962, semiconductor diode lasers have revolutionized communications and made possible information storage and retrieval in CDs, DVDs and Blu-ray devices. These diode lasers use inorganic semiconductors ...
