Polycrystalline cells are composed of multiple silicon crystals, which is a cheaper way to manufacture solar modules. Put simply, these cells are easier for a factory to produce, so they are less expensive. Polycrystalline cells are made by several methods, but most commonly with a cast of molten silicon.
Polyimide Tubing. Polyimide is a polymer thermoset plastic that has exceptional thermal stability, chemical resistance, and tensile strength. These characteristics make polyimide an ideal material for high-performance medical applications. The tubing is lightweight, flexible, and resistant to heat and chemical interaction.
