Hydrogen-discriminating nanocrystalline doped-tin-oxide room-temperature microsensor

Nanocrystalline mesoporous palladium activated tin oxide thin films as room-temperature hydrogen gas sensors.

A unique nanocrystalline, mesoporous PdO-SnO(2) film exhibiting high sensitivity and selectivity to hydrogen gas at room temperature has been developed.

Hydrogen-doped indium oxide/indium tin oxide bilayers for high-efficiency silicon heterojunction solar cells

The front transparent conductive oxide layer is a source of significant optical and electrical losses in silicon heterojunction solar cells because of the trade-off between free-carrier absorption and sheet resistance. We demonstrate that hydrogen-doped indium oxide (IO:H), which has an electron mobility of over 100 cm/V s, reduces these losses compared to traditional, low-mobility transparent ...

Hydrogen reduction of molybdenum oxide at room temperature

The color changes in chemo- and photochromic MoO3 used in sensors and in organic photovoltaic (OPV) cells can be traced back to intercalated hydrogen atoms stemming either from gaseous hydrogen dissociated at catalytic surfaces or from photocatalytically split water. In applications, the reversibility of the process is of utmost importance, and deterioration of the layer functionality due to si...
