    摘要: The invention pertains to a method of manufacturing a photovoltaic foil comprising a TCO layer, a photovoltaic layer, and a back electrode, which method comprises the following steps: providing a conductive temporary substrate; applying a TCO layer on the temporary substrate; applying a photovoltaic layer on the TCO by means of electrodeposition, with the current during the electrodeposition being supplied at least through the temporary substrate; applying a back electrode; if so desired, applying a permanent substrate; removing the temporary substrate. The crux of the invention is that the unit of the conductive temporary substrate and the TCO functions as electrode during the electrodeposition of the photovoltaic layer. Because of this, the rate of deposition of the photovoltaic layer can be increased compared with that of the prior art. Furthermore, a photovoltaic layer with a more homogenous layer thickness is obtained.

    摘要: The invention pertains to a solar cell unit comprising a back electrode, a photovoltaic (PV) layer, and, optionally, a front electrode, with part of the surface of the solar cell unit not generating any energy, characterised in that on at least a portion of the part of the solar cell unit which does not generate any energy a colouring layer is present, while at least a portion of the energy generating part of the solar cell unit is free of a colouring layer. Preferably at least 50%, more preferably, at least 85%, more preferably still, at least 90% of the energy generating part of the solar cell unit is free of a colouring layer. The solar cell unit may be either a wafer-based solar cell unit or a thin film solar cell unit. The colouring layer may be applied on, e.g., the optionally present grid and/or in the case of thin film solar cell units on the part of the surface of the solar cell unit which does not generate any energy as a result of the connection in series.The solar cell unit preferably is made by means of a process where the application of the colouring layer is integrated into the process.The invention provides a coloured solar cell unit where the application of the colour need not be at the expense of the solar cell unit's output.

    摘要: The invention relates to a photovoltaic cell, including at least a first junction between a pair of semiconducting regions (4-9). At least one of the pair of semiconducting regions includes at least part of a superlattice comprising a first material interspersed with formations of a second material. The formations are of sufficiently small dimensions so that the effective band gap of the superlattice is at least partly determined by the dimensions. An absorption layer (24-26) is provided between the semiconducting regions and the absorption layer comprises a material for absorption of radiation so as to result in excitation of charge carriers and is of such thickness that excitation levels are determined by the material itself. At least one of the effective energy bands of the superlattice and one of the excitation levels of the material of the absorption layer is selected to match at least one of the excitation levels of the material of the absorption layer and the effective energy band of the superlattice, respectively.

    摘要: It has been found that fibres can be spun in a simple manner from polyketone polymer solutions by making a thermoreversible gel from a solution of polyketone and a solvent for the polymer having a boiling temperature above 443 K, a melting temperature below 373 K, and a polymer dissolving temperature above 443 K. The thermoreversible gel forms as the solution is cooled. Because of the specific properties of the solvent in combination with the concentration of the polymer and its intrinsic viscosity, a permanently orientable thermoreversible gel is formed by cooling. The polymer crystallises on being cooled, optionally while still in the presence of the solvent. Preferably, so much polymer is dissolved as will give a product of the polymer concentration and �.eta.!.sup.0.5 (wherein �.eta.! represents the intrinsic viscosity of the polymer) of higher than 0.35 (dl/g).sup.0.5.
