Next, the ingots are sliced into wafers.
Depending on the type of silicon used, p-type or n-type silicon wafers may be produced.
After layering the p-type or n-type wafers, the material is capable of generating electricity from sunlight. Electrodes are attached to the wafers to conduct the flow of electricity. This is called a photovoltaic cell, or "solar cell."
 Although a single cell can generate small amounts of electricity, connecting many cells in a series will increase the voltage to an optimum level.
Tempered glass and sealants are assembled around the cells to protect them against the elements. The finished product is now called a photovoltaic module, or "solar module." |
