ABSTRACT: Experiments
described in this paper show that there is the photoconductive effect of
liquid, i.e. when light shines into a
sort of alkali, acid or salt solution, the conductivity of the solution will
increase. The mechanism of the effect is explained as follows. When hydrated
ions in the solution absorb photons with their high enough energies, they will
decompose to naked ions and water-molecules. The naked ions can reach an anode or a cathode more easily and
faster than the hydrated ions; It is possible that when a molecule in the solution
absorbs a photon with its high enough energy, it will decompose to negative and
positive ions. Based on the effect, a device producing hydrogen by the
solar-energy had been devised.
