摘要:
An inverted organic solar photovoltaic cell is described that may be fabricated onto rigid or flexible substrates using spray-on technology to apply the various layers of the cell. Indium tin oxide with a thin layer of cesium carbonate functions as the cathode for the novel inverted cells. An active layer of poly-3(hexylthiophene) and [6,6]-phenyl C61-butyric acid methylester having a thickness around 200nm to 600nm facilitates a high level of light transmittal through the cell. A modified PEDOT:PSS, made by doping a conductive polymer with dimethylsulfoxide (DMSO), functions as the anode. A method of forming the inverted organic solar photovoltaic cell is also described using gas-propelled spraying to achieve thin layers. After the layers are formed, the cell is sealed using a vacuum and temperature-based annealing and encapsulation with UV-cure epoxy.

摘要:
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.
