Photovoltaic wafers or cells, also known as solar cell wafers, use the photovoltaic effect to convert sunlight to electricity. These cells come in various types, from the non-crystalline amorphous silicon to the more efficient single-crystal monocrystalline silicon. Each type has different efficiency and price rates, catering to multiple needs and budgets.
The lower ASP for silicon WAFers is due to pressure from the solar and PV cell industries, and improvements in silicon wafer recovery processes have reduced demand for test waves for semiconductor manufacturing. In addition, the demand of silicone wafer manufacturers is booming, resulting in a tight supply and higher prices for wafers. [Sources: 3, 4, 7, 8]
