Beschreibung
Zusammenfassung:	One embodiment of the present invention provides a bifacial solar panel. The bifacial solar panel includes a first transparent cover on a first side of the solar panel, a second transparent cover on a second side of the solar panel, a plurality of solar cells sandwiched between the first cover and the second cover, and one or more lead wires for outputting power generated by the solar panel. The lead wires are positioned on an edge of the solar panel without shading the first and second sides of the solar panel. A respective solar cell comprises a photovoltaic structure, a first metal grid on the first side of the photovoltaic structure, which allows the solar cell to absorb light from the first side, and a second metal grid on the second side of the photovoltaic structure, which allows the solar cell to absorb light from the second side.
