From: Design and fabrication of six-volt vertically-stacked GaAs photovoltaic power converter
(a) I-V characteristics of the PPC device (the device with designated illumination area of 11.34 mm2) under different incident laser powers, (b) output power of the PPC device versus incident laser power (808 nm fiber-coupled laser source), the inset shows a picture of PPC. (c) open circuit voltage(square), operating voltage (triangle), conversion efficiency (circle) and fill factor (star)of PPC device as a function of the incident laser power; The inset shows the summary of calculated and measured Isc.
