By this method, the silicon is passed through the DSS ingot growth furnace and processed into pure quadratic silicon blocks.
How are solar cells made?
The production process from raw quartz to solar cells involves a range of steps, starting with the recovery and purification of silicon, followed by its slicing into utilizable disks – the silicon wafers – that are further processed into ready-to-assemble solar cells.
What is the efficiency of crystalline silicon solar cells?
Commercially, the efficiency for mono-crystalline silicon solar cells is in the range of 16–18% (Outlook, 2018). Together with multi-crystalline cells, crystalline silicon-based cells are used in the largest quantity for standard module production, representing about 90% of the world's total PV cell production in 2008 (Outlook, 2018).
Can molten silicon be used to make a solar cell?
This molten silicon is 99% pure which is still insufficient to be used for processing into a solar cell, so further purification is undertaken by applying the floating zone technique (FTZ). During the FTZ, the 99% pure silicon is repeatedly passed in the same direction through a heated tube.
How to make crystalline silicon for PV applications?
The most relevant methods for the production of crystalline silicon for PV applications are the Czochralski method for monocrystalline silicon and directional solidification method for multicrystalline silicon.
