BIFACIAL SOLAR CELL

摘要

PURPOSE: A bifacial solar cell is provided to form a tandem structure with high efficiency by using both sides of a transparent substrate as a solar cell. CONSTITUTION: A transparent substrate(111) includes a first surface and a second surface. A first transparent electrode(112) is formed on the first side of the transparent substrate. A first light absorbing layer(113) is formed on the first transparent electrode. A second transparent electrode(116) is formed on the first light absorbing layer. A first metal electrode pad(119) is formed on the exposed first transparent electrode. A third transparent electrode(122) is formed under the second surface of the transparent substrate.
