But Graetzel and his colleagues recently discovered that by substituting ionic liquids — liquids made up of
charged particles, imidazolium
iodide in this case — they could maintain the efficiency and pose no risk of evaporation.
Under intense illumination, the researchers found that
iodide ions — atoms stripped of an electron so they carry an electric
charge — migrated away from the illuminated region, and in the process apparently swept away most of the defects in that region along with them.
STIS uses three detectors: a cesium
iodide photocathode Multi-Anode Microchannel Array (MAMA) for 115 to 170 nm, a cesium telluride MAMA for 165 to 310 nm, and a
Charge Coupled Device (CCD) for 165 to 1000 nm.
