PROTECTIVE LAYER FOR THE BACK REFLECTOR OF A PHOTOVOLTAIC DEVICE.

摘要

A protective layer is disposed between a silver reflective electrode and a layer of transparent conductive oxide in a photovoltaic device so as to prevent oxidation of the silver. The protective layer may be continuous or discontinuous and may be fabricated from MgF2, Six Ny or Tix Ny where x and y are positive numbers.
