Latest Patents

Wen Ma holds a patent for "Low-cost solar cells and methods for fabricating low cost substrates for solar cells." This patent describes a process where substrates for solar cells are prepared by etching a plurality of metallurgical grade wafers. The method includes depositing an aluminum layer on the backside of each wafer, followed by a layer of hydrogenated silicon nitride on the front surface. The wafers are then annealed at elevated temperatures, and the hydrogenated silicon nitride is removed without disturbing the aluminum layer. A solar cell is subsequently fabricated on the front surface of the wafer, with the aluminum serving as the back contact of the cell.
