Journal ArticleDOI
High and Low Work Function Materials for Passivated Contacts
Frank Feldmann,Kurt-Ulrich Ritzau,Martin Bivour,Anamaria Moldovan,Siddharth Modi,Jan Temmler,Martin Hermle,Stefan W. Glunz +7 more
TL;DR: In this paper, the authors investigated possible contact materials having a high/low work function for passivated contacts, which enabled the realization of a double-sided contact Si solar cell featuring n-TOPCon on the front and p-type TOPCon at the rear side.
Journal ArticleDOI
Amorphous silicon carbide heterojunction solar cells on p-type substrates
TL;DR: In this article, the performance of silicon heterojunction (SHJ) solar cells is discussed in regard to their dependence on the applied amorphous silicon layers, their thicknesses and surface morphology.
Proceedings ArticleDOI
FIRING STABLE Al2O3/SiNx LAYER STACK PASSIVATION FOR THE FRONT SIDE BORON EMITTER OF N-TYPE SILICON SOLAR CELLS
TL;DR: In this article, the quality of the base material is of increasing importance for high-efficiency solar cells, and the PV industry tends to introduce advanced solar cell concepts, like passivated rear, selective emit-ters, etc.
Journal ArticleDOI
Towards the efficiency limits of multicrystalline silicon solar cells
Florian Schindler,Andreas Fell,Ralph Müller,Jan Benick,Armin Richter,Frank Feldmann,Patricia Krenckel,Stephan Riepe,Martin C. Schubert,Stefan W. Glunz,Stefan W. Glunz +10 more
TL;DR: In this paper, the authors present the state-of-the-art multicrystalline silicon photovoltaics with the TOPCon solar cell concept with a boron-diffused emitter and achieved a certified conversion efficiency of 22.3%.
Proceedings ArticleDOI
Advanced upconverter systems with spectral and geometric concentration for high upconversion efficiencies
Jan Christoph Goldschmidt,Philipp Löper,Stefan Fischer,Stefan Janz,Marius Peters,Stefan W. Glunz,Gerhard Willeke,Efrat Lifshitz,Karl Krämer,Daniel Biner +9 more
TL;DR: In this article, an advanced upconverter system concept was proposed to reduce the sub-bandgap losses of silicon solar cells, which avoids unwanted absorption by separating upconverster and fluorescent material with a selectively reflective photonic structure.
