Abstract

We propose a new, optically coupled tandem architecture with a silicon 'PVMirror' as the bottom cell. A silicon PVMirror is a curved silicon module with an integrated dichroic mirror that transmits near-infrared light to the silicon cells and reflects and focuses visible light onto a GaAs receiver. Simulating such a system with record GaAs and silicon cells and an ideal dichroic mirror shows the tandem efficiency can reach over 36% with no diffuse light and over 30% with 20% diffuse light. A sensitivity analysis indicates that the PVMirror tandem is most sensitive to the GaAs cell performance and dichroic mirror cut-off wavelength but relatively insensitive to the silicon cell performance.
