摘要:
A method of producing a crystalline semiconductor material includes feeding particles of the semiconductor material and/or a precursor compound of the semiconductor material into a gas flow, wherein the gas flow has a sufficiently high temperature to convert the particles of the semiconductor material from a solid into a liquid and/or gaseous state and/or to thermally decompose the precursor compound, condensing out and/or separating the liquid semiconductor material from the gas flow, and converting the liquid semiconductor material to a solid state with formation of mono- or polycrystalline crystal properties.

摘要:
In order to treat solar cells in an electroplating device, they can be inserted into a grid-like or tray-like picking-up device. They are thus mechanically held and electrical contact is made with them via contacts. Instead of individual solar cells, the picking-up devices are moved with a large number of inserted solar cells through the electroplating device for treatment. Electrical contact with the solar cells is in this case made via the contacts and the frame limbs on a projecting angle section together with edge strips of the pick-up. Contact rollers rest on the edge strips and are connected to an electrical power source.
