  • High efficiency micromorph tandem cells
    Patent number: 8846434
    Abstract: A method for manufacturing a micromorph tandem cell is disclosed. The micromorph tandem cell comprises a ?c-Si:H bottom cell and an a-Si:H top cell, an LPCVD ZnO front contact layer and a ZnO back contact in combination with a white reflector. The method comprises the steps of applying an AR—Anti-Reflecting—concept to the micromorph tandem cell; implementing an intermediate reflector in the micromorph tandem cell. The micromorph tandem cell can achieve a stabilized efficiency of 10.6%.
