PHOTOVOLTAIC MODULE CONFIGURATION

摘要

Improvements for a photovoltaic module (PVM) include the use of a micro-embossed, reflective optical film located in areas of the PVM not covered by the solar cells. The optical film is configured to reflect light incident upon the PVM onto the solar cells and may be formed from a polymeric material. Further enhancements include the use of a compliant heat conducting polymeric film on back sides of the solar cells and a heat conductive polymeric film deposited on an aluminum foil to form a composite film, which effects heat transfer from the solar cell junctions and improves cell efficiency. A top glass with selective frequency and anti-reflective coatings may also be used. Further, improved interconnects for the solar cells eliminate sharp edges, helping to avoid any potential for encapsulant tearing or tab "push-through" and resultant shorting during lamination.
