2017 5th International Workshop on Low Temperature Bonding for 3D Integration (LTB-3D) | 2017

The electrical properties of n-Si/ITO/n-Si, n-Si/ITO/p-Si, and p-Si/ITO/n-Si junctions fabricated by surface activated bonding (SAB) were investigated. The current-voltage (I-V) characteristics of n-Si/ITO/n-Si, n-Si/ITO/p-Si, and p-Si/ITO/n-Si junctions showed excellent linearity. The interface resistance of n-Si/ITO/p-Si junctions was found to be 0.0249 O·cm2, which is the smallest value observed in all the samples.

Layered CdTe nanoparticles were deposited on surfaces of n-on-p crystalline Si solar cells. Their short-circuit current and conversion efficiency were enhanced due to the nanoparticle deposition. Measurements of reflectance and external-quantum-efficiency spectra as well as atomic-force-microscope observations implied that the enhancements in cell performances were attributable to textured structures of the deposited nanoparticle layers.
