How does reflection affect bifacial transmission in solar cells?

Transmission, subsequent reflection on module cover layers and a second absorption of light in the solar cell leads to additional gains in the range of 0.5 – 0.8% for bifacial cells in modules with reflecting rear cover materials (i.e. white backsheets). Transmission gains in modules with absorbing or transparent rear covers can be neglected.
