Title: Jochen Rentsch and Solar Cell Manufacturing
Introduction
Jochen Rentsch is an inventor associated with Freiburg, Germany. His patent work includes a method for producing a solar cell with a rear-side contact incorporating a tunnel barrier.
Latest Patents
Rentsch is credited with 1 patent, titled “Method for Producing a Solar Cell.” The disclosed method begins with a monocrystalline wafer that has front and rear sides and is provided with silicon and a dopant. A tunnel barrier is formed on the wafer, followed by deposition of a doped polycrystalline or amorphous layer containing silicon. Gas-phase etching removes this layer from the front side, supporting the formation of a solar cell with a rear-side contact.
Career Highlights
Rentsch’s professional affiliations include Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V. and Ultra High Vacuum Solutions Ltd. His patent reflects work on semiconductor processing techniques relevant to solar-cell manufacturing.
