HIGH EFFICIENCY MICROMORPH TANDEM CELLS

摘要

A method for manufacturing a micromorph tandem cell is disclosed. The micromorph tandem cell comprises a µc-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%.
