Abstract

In this paper, GaInP/GaAs/InGaAsN/Ge four-junction solar cells are designed and optimized. The efficiency of the cells reaches 32.84% in AM0 spectrum and non-concentrated light. Solcore is used to establish a model, which mainly explores the influence of doping and thickness of sub-cell on the quantum efficiency and J-V characteristics of the cell. The base doping of GaInP cell and Ge cell was optimized to be 5×10¹⁷ cm^-3, and current matching was achieved by adjusting the base thickness. The reflectance of MgF₂/ZnS double-layer Anti-Reflective Coating (ARC) was compared with that of MgF₂/ SiC /ZnS triple-layer anti-reflective coating. Under the action of a three-layer ARC, the efficiency was improved by about 1.4%. After optimization, the peak efficiency is 42.8% under 700 times of concentrated light.
