Amorphous Silicon/Crystalline Silicon Heterojunction Solar Cells

Christophe Ballif, Antoine Descoeudres, Stefaan De Wolf

Silicon heterojunction solar cells are crystalline silicon-based devices in which thin amorphous silicon layers deposited on the wafer surfaces serve as passivated, carrier-selective contacts. The success of this technology is attributable to the ability o ...

Back-Contacted Silicon Heterojunction Solar Cells With Efficiency >21%

Christophe Ballif, Antoine Descoeudres, Bertrand Yves Paul Paviet-Salomon, Jonas Geissbühler, Stefaan De Wolf, Andrea Tomasi, Silvia Martin de Nicolas Agut

We report on the fabrication of back-contacted silicon heterojunction solar cells with conversion efficiencies above 21%. Our process technology relies solely on simple and size-scalable patterning methods, with no high-temperature steps. Using in situ sha ...

Hydrogen-doped indium oxide/indium tin oxide bilayers for high-efficiency silicon heterojunction solar cells

Christophe Ballif, Antoine Descoeudres, Corsin Battaglia, Stefaan De Wolf, Nicolas Badel, Loris Barraud

The front transparent conductive oxide layer is a source of significant optical and electrical losses in silicon heterojunction solar cells because of the trade-off between free-carrier absorption and sheet resistance. We demonstrate that hydrogen-doped in ...

Record Infrared Internal Quantum Efficiency in Silicon Heterojunction Solar Cells With Dielectric/Metal Rear Reflectors

Christophe Ballif, Antoine Descoeudres, Stefaan De Wolf

Inserting a dielectric between the absorber and rear metal electrode of a solar cell increases rear internal reflectance by both limiting the transmission cone and suppressing the plasmonic absorption of light arriving outside of the cone. We fabricate rea ...

High-efficiency Silicon Heterojunction Solar Cells: A Review

Christophe Ballif, Stefaan De Wolf, Antoine Descoeudres

De Gruyter, De Gruyter2012

A-Si:H/c-Si heterojunctions: a future mainstream technology for high-efficiency crystalline silicon solar cells ?

Christophe Ballif, Antoine Descoeudres, Stefaan De Wolf, Loris Barraud

In this contribution, we shortly review the main features of amorphous/crystalline silicon heterojunction (SHJ) solar cells, including interface defects and requirements for high quality interfaces. We show how a process flow with a limited number of proce ...

Improved amorphous/crystalline silicon interface passivation by hydrogen plasma treatment

Christophe Ballif, Antoine Descoeudres, Stefaan De Wolf, Loris Barraud, Benjamin Strahm, Jakub Holovsky, Johannes Peter Seif, Bénédicte Demaurex

Silicon heterojunction solar cells have high open-circuit voltages thanks to excellent passivation of the wafer surfaces by thin intrinsic amorphous silicon (a-Si:H) layers deposited by plasma-enhanced chemical vapor deposition. We show a dramatic improvem ...
