I am geting confused ( ) that what is the difference between photo-conductive and photo-voltic devices.

as boath devices depends on the intensity of light, boath depends on no of charge cariers,...
In boath cases there is movement of charge cariers , so there is a flow of current, then what is the difference :(

Imho the difference you are looking for is that photoconductive devices only change their conductivity when exposed to light while photovoltaics actually generate electrical power by the means of voltage induced by EMR.
