III-V or II-VI compound semiconductor films on graphitic substrates

A composition of matter, in particular a photovoltaic cell, comprising: at least one core semiconductor nanowire on a graphitic substrate, said at least one core nanowire having been grown epitaxially on said substrate wherein said nanowire comprises at least one group III-V compound or at least one group II-VI compound or at least one group IV element; a semiconductor shell surrounding said core nanowire, said shell comprising at least one group III-V compound or at least one group II-VI compound or at least one group IV element such that said core nanowire and said shell form a n-type semiconductor and a p-type semiconductor respectively or vice versa; and an outer conducting coating surrounding said shell which forms an electrode contact.

Solar cells

A composition of matter comprising at least one nanowire on a graphitic substrate, said at least one nanowire having been grown epitaxially on said substrate, wherein said nanowire comprises at least one group III-V compound or at least one group II-VI compound or comprises at least one non carbon group (IV) element.

Compositions comprising epitaxial nanowires on graphene substrates and methods of making thereof

A composition of matter comprising a plurality of nanowires on a substrate, said nanowires having been grown epitaxially on said substrate in the presence of a metal catalyst such that a catalyst deposit is located at the top of at least some of said nanowires, wherein said nanowires comprise at least one group III-V compound or at least one group II-VI compound or comprises at least one non carbon group IV element; and wherein a graphitic layer is in contact with at least some of the catalyst deposits on top of said nanowires.
