On the impact of the metal work function on the recombination in passivating contacts using quasi-steady-state photoluminescence

Autor: Anh Huy Tuan Le, Johannes P. Seif, Thomas Allen, Andres Cuevas, Robert Dumbrell, Christian Samundsett, Ziv Hameiri

Publikováno v: 2019 IEEE 46th Photovoltaic Specialists Conference (PVSC).

Understanding the impact of metal contacts on the recombination within a passivated silicon wafer is crucial for the optimization of various photovoltaic devices such as passivating-contact-based solar cells. To investigate the effect of the metal wo

Nanocrystalline Silicon Carrier Collectors for Silicon Heterojunction Solar Cells and Impact on Low-Temperature Device Characteristics

Autor: Franz-Josef Haug, Quentin Jeangros, Christophe Ballif, Johannes P. Seif, Stefaan De Wolf, Andrea Tomasi, Nicolas Wyrsch, Gizem Nogay, Yannick Riesen

Publikováno v: IEEE Journal of Photovoltaics. 6:1654-1662

Silicon heterojunction solar cells typically use stacks of hydrogenated intrinsic/doped amorphous silicon layers as carrier selective contacts. However, the use of these layers may cause parasitic optical absorption losses and moderate fill factor (
