Abstract
A hybrid photovoltaic cell comprising a composite substrate of a nanotube or nanorod array of metal oxide infiltrated with a monomer precursor and subsequently polymerized in situ via UV irradiation. In an embodiment, the photovoltaic cell comprises an electron accepting TiO2 nanotube array infiltrated with a photo-sensitive electron donating conjugated polymer. The conjugated polymer may be formed in situ through UV irradiation polymerizing a monomer precursor such as 2,5-diiodothiophene (DIT).
