Title: Innovations of John Kessler in Solar Technology
Introduction
John Kessler is a notable inventor based in Nantes, France. He has made significant contributions to the field of solar technology, particularly in the development of copper indium gallium diselenide (CIGS) solar cells. With a total of 2 patents, Kessler's work focuses on improving the efficiency and production processes of thin-film solar cells.
Latest Patents
Kessler's latest patents include a method and apparatus for in-line process control of the CIGS process. This invention involves an in-line production apparatus and a method for composition control of CIGS solar cells fabricated by a co-evaporation deposition process. The deposition conditions are designed to transform a deposited Cu-excessive overall composition into a Cu-deficient overall composition, resulting in the final CIGS film. The process utilizes substrates with a molybdenum layer that move through the process chamber at a constant speed. Sensors detect the transition from copper-rich to copper-deficient composition on a substrate by measuring a physical parameter related to the transition. A controller connected to these sensors adjusts the fluxes from the evaporant sources to ensure a uniform composition and thickness of the CIGS layer across the substrate's width.
Another significant patent involves the development of thin-film solar cells of the CIGS type, which utilize two integrally formed buffer layers. The first is an ALD Zn(O,S) buffer layer on top of the CIGS layer, and the second is an ALD ZnO buffer layer on top of the first buffer layer. Both buffer layers are deposited in the same process step using atomic layer deposition (ALD). This technology also encompasses a method for producing the cell and a process line for manufacturing the cell structure.
