Amorphous Silicon/Crystalline Silicon Heterojunction Solar Cells

2014
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 of amorphous silicon to passivate dangling bonds—thereby removing surface recombination sites ...

Amorphous silicon/crystalline silicon heterojunctions for solar cells

Journal of Non-Crystalline Solids, 2002
Amorphous silicon/crystalline silicon (c-Si) heterojunctions are studied by contactless transient photoconductivity measurements at the microwave frequency range. Excellent passivation of the n-type crystalline silicon (n c-Si) surface by n-type, hydrogenated amorphous silicon (n a-Si:H) films is observed. The influence of band offsets is discussed. It

Heterojunction Silicon Based Solar Cells

2012
Heterojunction (HJ) silicon solar cells use crystalline silicon wafers for both carrier transport and absorption, and amorphous and/or microcrystalline thin silicon layers for passivation and junction formation. The top electrode is comprised of a transparent conductive oxide (TCO) layer in combination with a metal grid.

Hole-blocking TiO2/silicon heterojunction for silicon photovoltaics

70th Device Research Conference, 2012
Narrow bandgap heterojunctions on crystalline silicon such as Si/Si 1−x Ge x are now in widespread use, but to date there has been little progress on widegap heterojunctions on silicon. In this abstract, we report: (i) TiO 2 /Si heterojunction with a band alignment which blocks holes from silicon but freely passes electrons, and (ii) the application ...

Amorphous/porous heterojunction on thin microcrystalline silicon

Journal of Non-Crystalline Solids, 2000
Abstract In this work we present a study of the fabrication of the junction between amorphous and porous silicon. Porous silicon was obtained by electrochemical etching of a 2 μm thick crystalline n-doped layer obtained by thermal recrystallisation of amorphous silicon deposited using chemical vapour deposition (CVD). A thin amorphous silicon emitter

Heterojunctions based on Silicon Carbide

AIP Conference Proceedings, 2007
In addition to possessing unique electrical properties, silicon carbide (SiC) can crystallize in different modifications (polytypes). Having the same chemical nature, SiC polytypes may significantly differ in their electrical parameters. In recent years, the world’s interest in fabrication and study of heteropolytype structures based on silicon carbide

Proton Damage in Amorphous Silicon/Crystalline Silicon Heterojunction Solar Cells

Journal of The Electrochemical Society, 2006
The applicability of amorphous silicon/crystalline silicon (a-Si:H/c-Si) heterojunction solar cells for their use in space environment was tested. The cells were subject to proton irradiation at energies between 0.8 and 4 MeV. The optical and electrical parameters were measured.

Local Photovoltaic Properties of Graphene–Silicon Heterojunctions

physica status solidi (b), 2018
Interfacing of materials with different dimensionalities becomes increasingly relevant for many applications which can utilize the exceptional properties of low‐dimensional materials on one hand, and build‐up on the existing production know‐how for bulk (3D) materials on the other. Numerous appealing possibilities are offered by such combinations.

Solar cells with gallium phosphide/silicon heterojunction

AIP Conference Proceedings, 2015
One of the limitations of current amorphous silicon/crystalline silicon heterojunction solar cells is electrical and optical losses in the front transparent conductive oxide and amorphous silicon layers that limit the short circuit current. We propose to grow a thin (5 to 20 nm) crystalline Gallium Phosphide (GaP) by epitaxy on silicon to form a more ...
