Beschreibung
Zusammenfassung:	The utility model discloses a high-efficiency flexible thin-film solar cell. A back electrode is arranged on one side of a thinned epitaxial substrate and is bonded onto the flexible thin-film substrate, an epitaxial structure is arranged on the other side of the thinned epitaxial substrate, an ohmic contact layer is arranged on the epitaxial structure, a front side grid line electrode is arranged on the ohmic contact layer and selectively etches the ohmic contact layer, and an antireflection film is arranged in the etching zone. The thin-film solar cell provided by the utility model is high in conversion efficiency, excellent in reliability and flexibility, and reduced in weight.
