ABSTRACT:
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.
