"improving the hydrogenation process of the POLO junctions by a rear-side dielectric layer stack made of aluminum oxide and silicon nitride (Al2O3/SiNx/Al2O3) may further raise the device’s efficiency for the same standard thickness. This configuration was found to have the potential to reach an efficiency of up to 29.1%"
