Abstract: The present disclosure regards a method for coupling a graphene layer to a substrate having at least one hydrophilic surface, the method comprising the steps of providing the substrate having at least one hydrophilic surface, depositing on the hydrophilic surface a layer of a solvent selected in the group constituted by acetone, ethyl lactate, isopropyl alcohol, methylethyl ketone and mixtures thereof and depositing on the solvent layer a graphene layer. It moreover regards an electronic device comprising the graphene/substrate structure obtained.

Abstract: Solar thin film modules are provided with reduced lateral dimensions of isolation trenches and contact trenches, which provide for a series connection of the individual solar cells. To this end lithography and etch techniques are applied to pattern the individual material layers, thereby reducing parasitic shunt leakages compared to conventional laser scribing techniques. In particular, there may be series connected solar cells formed on a flexible substrate material that are highly efficient in indoor applications.
