초록

We investigated the n-type δ-doping activation of the tunneling junctions of Si nanolayers for silicon tandem cell applications. The thin film growth of pn junction with the inclusion of phosphorus monolayer was performed by plasma-enhanced chemical vapor deposition with the implement on 6-inch wafers of p-Si microtextured substrates. The rapid thermal annealing processes with various temperatures were performed to activate the δ-doped layer. The activation was confirmed by the electron spin resonance with Lande factor g=2.006085 for the delocalized conduction electron from the phosphorus δ-doped layer at the magnetic field of 3357.5 Gauss. The tunneling junction shows the Ohmic character at the low voltage and the Schottky character at the high voltage bias.
