ABSTRACT:
Solar cell construction having a body formed essentially of silicon and having a surface with a photovoltaic junction applied thereon. An anti-reflection coating is formed on the surface. A transparent protective cover is provided. A cut-on filter is carried by the cover for reflecting solar energy below approximately 350 nanometers. A layer of substantially transparent cement is used for securing the protective cover to the body so that it overlies the junction and the anti-reflection coating. The cut-on filter includes a stack of high and low index layers for reflecting solar energy in the ultra-violet region of 350 nanometers and below and also may include at least one additional layer of material of absorbing ultraviolet energy below 350 nanometers which passes through the high and low index layers above it.
