Title: Method of manufacturing a photovoltaic foil
Inventor: MIDDELMAN ERIK
IPC: H01L31/046
Filed: 2001-03-28
Granted: 2012-01-10
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.

Abstract: During the growth and study of NSCs, a range of molecules present on the surface of multipotent neural stem and progenitor cells (NSCs) were identified. These markers were identified using a number of human and murine neural stem cell lines, including retinal stem cells (RSCs). The NSC-specific markers identified included gene products as well as non-protein molecules and sugar epitopes not directly coded in the genome. Together with surface markers which were determined to be absent from the surface of hNSCs, the molecules described herein provide a means to enrich for neural stem cells, or neural progenitor subpopulations, particularly using combinatorial cell sorting strategies. These same molecules also represent targets for pharmacological manipulation of NSC populations and subpopulations, both in vivo and ex vivo. Furthermore, these molecules provide potential targets for therapeutic manipulation of other neural precursor-related cell types including malignant conditions as well as other diseases originating from, or preferentially affecting, various uncommitted or replication-competent cell types.
