Abstract: The invention relates to a metal powder intended for use in an additive manufacturing process, which consists of steel particles having an average diameter of 5-150 ?m and consisting of, in mass %, C: 0.15-1.0%, N: 0.15-1.0%, Si, 0.1-2.0%, Mn: 10-25%, Cr: 5-21%, Mo: 0.1-3.0%, Ni: ?5%, remainder of iron and unavoidable impurities. The metal powder has a flow rate determined in accordance with DIN EN ISO 4490 of less than 30 sec/50 g. Using a metal powder according to the invention, reliable high-load-bearing components can be produced by additive manufacturing. Accordingly, a metal powder according to the invention is particularly suitable for the manufacture of machine elements that are exposed to high loads and of medical components that are used in or on the human or animal body. The invention also provides a method which reliably allows components with optimised mechanical properties to be manufactured from metal powder according to the invention on the basis of an additive manufacturing process.

Abstract: A solar cell device includes a solar cell with a semiconductor having at least one p-doped region and at least one n-doped region. Electrical p-contacts and n-contacts on the back of the solar cell are connected to correspondingly doped regions of the semiconductor. At least one p-busbar is connected to the electrical p-contacts and at least one n-busbar is connected to the electrical n-contacts. The busbars collect current of the electrical contacts and form a direction of longitudinal extension and a connection arrangement providing an electrically conductive connection of at least one busbar of the solar cell to at least one busbar of an adjacent solar cell. The connection arrangement includes at least one first connection section extending essentially perpendicular to the direction of longitudinal extension of the busbars, which connection section, by way of connection regions, is connected in a point-like manner with at least one busbar.
