From: Design and fabrication of six-volt vertically-stacked GaAs photovoltaic power converter
(a) Simulated J-V and P-V curves of sub-cells with an incident 808 nm laser power density of 2 W/cm2, the inset shows the conversion efficiency of sub-cells under different input laser power densities; (b) the open circuit voltage of sub-cells and the total of conversion efficiency of the six sub-cells under different input laser power densities.
