Does someone know a cost effective, easy way to build a fuctional device that permits electrochemical disociation of water into Oxygen and Hydrogen by means of direct solar radiation? I don’t mean a photovoltaic cell atached to a couple of electrodes. My idea is starting to study this method of solar energy storage at home. Do you think it’s possible?

The National Renewable Energy Lab has a number of alternative to the traditional hydrogen production with electrods. Given your constraint of focusing on water to hydrogen conversion (2H2O — 2H2 + O2) and use of direct solar energy, your best bet is a semiconductor or a multi-junction semiconductor system described in this paper:
