The present invention relates to a photovoltaic module structureand to a method for establishing an electrically conductive connection between two spaced contact layers', in particular in the photovoltaic module structureaccording to the invention. The production method is particularly simple and economical and the photovoltaic module structureaccording to the invention enables a significant gain in efficiency.

Photovoltaic module structure and method for producing an electrically conductive connection

The invention relates to a process for producing a glass sheetcoated with a semiconductor material, which comprises the steps (a) production of a glass strip in a float bathcontaining liquid tin; (b) discharge of the glass strip from the float bathand optionally coating of the glass strip with a transparent, electrically conductive intermediate layer; (c) transfer of the uncoated or coated glass strip into a deposition chamberfor the physical deposition of the semiconductor material from the gas phase; and (d) coating of the coated or uncoated glass strip from step (c) with the semiconductor material by physical deposition of the semiconductor material from the gas phase at a gas pressure of at least 0.1 bar. The invention additionally relates to an apparatus for producing a glass strip coated with a semiconductor material, a process for producing a solar cell or a solar module and also a solar cell or a solar module which can be obtained by this process.
