The conductive sheet allows the DC energy to flow between solar cells, increasing the voltage and allowing for the connection of CdTe panels into photovoltaic (PV) systems. These layers require the deposition of a metal layer or carbon paste,introdu ing copper (Cu) to create condu s,including polymers,fluoropolymers,and polyester. Protection: The primary function of a PV backsheet is to rotect the internal components. The PV cell is composed of semiconductor material; the “semi” means that it can conduct electricity better than an insulator but not as well as a good conductor like a metal. There are several different semiconductor materials used in PV cells. When the semiconductor is exposed to light, it absorbs. Thin film PV modules are typically processed as a single unit from beginning to end, where all steps occur in one facility.
