Definition: Bifaces, also known as "bifacial cells," are a type of photovoltaic cell that is fabricated using a thin film of silicon on a metal wafer. These cells are used in solar panels and other photovoltaic systems to convert sunlight into electricity. The term "bifaceted" refers to the fact that they have two layers of semiconductor material, one with a positive charge and one with a negative charge, which allows them to absorb light from both directions.
