A germanium multi-junction solar cell and a method of fabricating the same

Abstract

Disclosed are a germanium multi-junction solar cell and a manufacturing method thereof. The germanium multi-junction solar cell comprises a Ge sub-cell, an InGaAs sub-cell, an InGaAsP sub-cell and an InAlGaP sub-cell which are sequentially and laminatedly arranged. The germanium multi-junction solar cell and the manufacturing method thereof can reduce the manufacturing cost of the germanium multi-junction solar cell, improve the photoelectric conversion efficiency of the germanium multi-junction solar cell, and realize the thin film and flexibility of the germanium multi-junction solar cell.
