Estimating the term…
A method of producing a transparent electrode suitable for use in an organic semiconductor photovoltaic device. First and second silanes (3) are deposited from the vapour phase on a substrate (1) and bind to the surface of the substrate. A metal film (4) is then deposited from the vapour phase and binds to both the first and second silanes so as to produce a transparent metal layer having a thickness which is no greater than about 15 nanometres. The first silane is a non-amino functional silane and the second silane is an aminofunctional silane. The electrode may be flexible, using a polymer substrate (1). The metal film (4) may be provided with a plurality of apertures (5), provided for example by masking the substrate with microspheres (2) while depositing the metal and subsequently removing the microspheres, and/or annealing the metal so that apertures appear.
A method of producing a transparent electrode suitable for use in a photovoltaic device, comprising the steps of co-depositing on a transparent substrate, from the vapour phase, first and second silanes that bind to the surface of the substrate, and subsequently depositing from the vapour phase a metal film which binds to both the first and second silanes so as to produce a transparent metal layer having a thickness which is no greater than 15 nanometres, wherein the first silane is a non-amino functional silane and the second silane is an aminofunctional silane.
