Asymmetric band offsets in silicon heterojunction solar cells: Impact on device performance

Christophe Ballif, Antoine Descoeudres, Stefaan De Wolf, Loris Barraud, Johannes Peter Seif, Ugur Deneb Menda

Amorphous/crystalline silicon interfaces feature considerably larger valence than conduction band offsets. In this article, we analyze the impact of such band offset asymmetry on the performance of silicon heterojunction solar cells. To this end, we use si ...

Electrical Investigation of Porous Silicon/p-Si Heterojunction Prepared by Electrochemical Etching

Mario Andres Chavarria Varon

We presented the conduction mechanism investigation of porous silicon/p-Si heterojunction fabricated on low resistivity crystalline silicon by electrochemical anodization. Measurements of the current - voltage I(V) and capacitance - voltage C(V) characteri ...

Ultrafast Band Structure Control of a Two-Dimensional Heterostructure

Jens Christian Johannsen

The electronic structure of two-dimensional (2D) semiconductors can be significantly altered by screening effects, either from free charge carriers in the material or by environmental screening from the surrounding medium. The physical properties of 2D sem ...

Atomic Scale Observation of Chemical and Electronic Properties of Metal-Oxide Surfaces

Christian Alexander Stephan Dette

To meet the future global energy demand - an estimated additional 10 terawatts (TWs) per year in 2050 - a diversification of energy sources and fuels is needed. Solar energy represents a prominent alternative energy source. An important material for these ...

Increased Photoconductivity Lifetimes in GaAs Nanowires via n-Type and p-Type Shell Doping

Anna Fontcuberta i Morral, Federico Matteini, Francesca Amaduzzi

Reliable doping in GaAs nanowires is essential for the development of novel optoelectronic devices. Previously, GaAs nanowires have been shown to exhibit extremely short photoconductivity lifetimes of a few picoseconds due to their high surface recombinati ...

Strategies for Doped Nanocrystalline Silicon Integration in Silicon Heterojunction Solar Cells

Christophe Ballif, Aïcha Hessler-Wyser, Antoine Descoeudres, Jonas Geissbühler, Stefaan De Wolf, Gizem Nogay, Martial Duchamp, Johannes Peter Seif, Simon Hänni, Martin Ledinsky, Niels Holm

Carrier collection in silicon heterojunction (SHJ) solar cells is usually achieved by doped amorphous silicon layers of a few nanometers, deposited at opposite sides of the crystalline silicon wafer. These layers are often defect-rich, resulting in modest ...
