Full-Area Passivating Contacts with High and Low Thermal Budgets: Solutions for High Efficiency c-Si Solar Cells

Gizem Nogay

Today more than 90% of the global PV market is covered by c-Si solar cells which are limited by recombination losses at the metal-semiconductor interface. This recombination path can be avoided by separating the metal from the c-Si wafer by introducing a b ...

Pipeline and SAR ADCs for Advanced Nodes

Kyojin Choo

The switched-capacitor SAR architecture has benefited tremendously from technology scaling. We first present a charge-injection-based SAR architecture that shrinks the die area needed for a SAR ADC and achieves outstanding energy efficiency. We go on to di ...
