Although crystalline PV cells dominate the market, cells can also be made from thin films—making them much more flexible and durable. One type of thin film PV cell is amorphous silicon (a-Si) which is produced by depositing thin layers of silicon on to a glass substrate. The result is a very thin and flexible cell which uses less than 1% of the silicon needed for a crystalline cell.
In addition to the technical process, the polysilicon plant of the Siemens method also has a relatively large investment. If the process starts from the production of trichlorosilane from metal silicon to polysilicon, a 1,000-ton plant will need to
