Electrical characteristics of Ag-PS interfaces under ambient humidity were
investigated. The humidity-voltaic effect, i.e. the generation of open-circ
uit voltage in Ag-PS interface in humid atmosphere (up to 200 mV at 90% rel
ative humidity) is discovered. Humidity-stimulated voltage generation is ma
inly caused by hydrogen component of water-vapour of ambient. The possible
mechanism related with H-stimulated generation of voltage in Ag-PS interfac
e is suggested. (C) 2001 Elsevier Science B.V. All rights reserved.
