Abstract
The invention refers to a hybrid device, monolithically integrating a photoanode with a silicon photovoltaic cell, capable of splitting water into hydrogen and oxygen when irradiated by visible or UV light; the invention also refers to a method for producing the hybrid device.
Claims12
A hybrid device monolithically integrating a photoanode and a commercial silicon (Si) photovoltaic cell, characterized in that the photoanode is made of a InGaN layer epitaxially grown over a (111) crystallographic planes of p-type silicon, and in that quantum dots of InN are produced over an exposed surface of the InGaN layer, said quantum dots having a ratio of height/diameter lower than 0.25.
