2 · The issue with the bill''s language is that no one has a genuine domestic supply chain — which the senators previously argued should begin at the wafer stage — except, of course, First Solar (which manufactures thin-film modules) and Qcells (which will be the only silicon solar manufacturer in the United States to have its own domestic wafer supply).
To make a silicon solar cell, blocks of crystalline silicon are cut into very thin wafers. The wafer is processed on both sides to separate the electrical charges and form a diode, a device that allows current to flow in only one direction. The diode is sandwiched between metal contacts to let the electrical current easily flow out of the cell.
