Abstract
Atomic-layer-deposited aluminum oxide (AlOx) layers are implemented between the phosphorous-diffused n+-emitter and the Al contact of passivated emitter and rear silicon solar cells. The increase in open-circuit voltage Voc of 12 mV for solar cells with the Al/AlOx/n+-Si tunnel contact compared to contacts without AlOx layer indicates contact passivation by the implemented AlOx. For the optimal AlOx layer thickness of 0.24 nm we achieve an independently confirmed energy conversion efficiency of 21.7% and a Voc of 673 mV. For AlOx thicknesses larger than 0.24 nm the tunnel probability decreases, resulting in a larger series resistance.
