Annealing of Silicon Heterojunction Solar Cells: Interplay of Solar Cell and Indium Tin Oxide Properties

Christophe Ballif, Raphaël François Lemerle, Mathieu Gérard Boccard, Jan Haschke, Brahim Aissa

In this paper, we report the evolution of silicon heterojunction solar cell properties focusing, in particular, on the indium tin oxide (ITO) layers upon consecutive thermal annealing. We find that the charge carrier density

Gallium Nitride as Transparent Electron-Selective Contact in Silicon Heterojunction Solar Cells

Christophe Ballif, Mathieu Gérard Boccard, Angela Nicole Fioretti, Tzu-Chin Chang Chien, Yashi Xiao

Carrier-selective, passivating contacts have allowed silicon heterojunction (SHJ) cells to reach recordbreaking efficiencies particularly in all-back-contacted designs. However, two-side-contacted SHJ cell efficiency has been limited due in part to parasit ...

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 ...
