what should be said.
Definition: Biface is a type of rock formation that forms when two or more layers of sedimentary rocks rub together, resulting in the formation of a single layer. The biface can be either vertical (like a cliff) or horizontal (like a hill). Bifaces are often found on the surface of mountains and other large bodies of water.
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.
