T3 - 2017 IEEE 44th Photovoltaic Specialist Conference, PVSC 2017īT - 2017 IEEE 44th Photovoltaic Specialist Conference, PVSC 2017 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. 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 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. 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.ĪB - We propose a new, optically coupled tandem architecture with a silicon 'PVMirror' as the bottom cell. 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. At room temperature (300 K) the dependency of the direct gap on aluminum content x can be calculated by the equation (Sadao Adachi: GaAs and Related. N2 - We propose a new, optically coupled tandem architecture with a silicon 'PVMirror' as the bottom cell.
