What Are Solar Cell Wafers?
Solar cell wafers are semiconductor substrates used to convert sunlight into electrical energy through the photovoltaic effect. They serve as the foundation for photovoltaic devices by providing the crystalline structure on which p-n junctions, anti-reflective coatings, and conductive contacts are fabricated. While monocrystalline and polycrystalline silicon remain the most widely used materials, advanced compound semiconductors such as gallium arsenide (GaAs), cadmium telluride (CdTe), cadmium sulfide (CdS), and indium phosphide (InP) are increasingly used for high-efficiency and specialized solar cell applications.
UniversityWafer supplies solar cell wafers and photovoltaic substrates for renewable energy research, prototype development, and commercial manufacturing. Custom wafer diameters, thicknesses, crystal orientations, conductivity types, and polishing options are available to support virtually any photovoltaic project.
