Study shows pressure induces unusually high electrical conductivity in polyiodide

Wednesday, March 20, 2019 - 06:30 in Physics & Chemistry

A study into the effects of high mechanical pressure on the polyiodide TEAI showed that it brings unusually high electrical conductivity starting from insulating state, suggesting that the material may be useful as a switchable semiconductor. This system could represent an alternative to gel electrolytes and ionic liquids in dye-synthesized solar cells. The paper, "Pressure-induced Polymerization and Electrical Conductivity of a Polyiodide," has been published in Angewandte Chemie.
