The invention concerns a photoactive nanocomposite ( 3 ) comprising at least one donor-acceptor couple of semiconductor elements. One of the elements is made of doped nanowires ( 7 ) with sp3 structure, and the other of the elements is an organic compound ( 8 ). The elements are supported by a device substrate ( 1 ). The invention also concerns a production method. According to a first embodiment, after their growth, the nanowires ( 7 ) are retrieved, functionalised and solubilised in the organic component ( 8 ). The mixture is deposited by coating on a device substrate. According to a second embodiment, the nanowires ( 7 ) are formed on a growth substrate ( 5 ) which is also the device substrate. The organic component ( 8 ) is combined with the nanowires ( 7 ) so as to form an active layer ( 3 ). Such a photoactive nanocomposite ( 3 ) allows production of a photovoltaic cell. |
