Heterojunction Silicon Microwire Solar Cells [PDF]

Nano Letters, 2012
We report radial heterojunction solar cells of amorphous silicon on crystalline silicon microwires with high surface passivation. While the shortened collection path is exploited to increase the photocurrent, proper choice of the wire radius and the highly passivated surface prevent drastic decrease in the voltage due to high surface-to-volume ratio ...

Prediction of sub-pyramid texturing as the next step towards high efficiency silicon heterojunction solar cells [PDF]

Nature Communications, 2023
The interfacial morphology of crystalline silicon/hydrogenated amorphous silicon (c-Si/a-Si:H) is a key success factor to approach the theoretical efficiency of Si-based solar cells, especially Si heterojunction technology.

Investigation of Graphene Single Layer on P-Type and N-Type Silicon Heterojunction Photodetectors [PDF]

Sensors
Photodetectors are of great interest in several technological applications thanks to their capability to convert an optical signal into an electrical one through light–matter interactions. In particular, broadband photodetectors based on graphene/silicon

A cost roadmap for silicon heterojunction solar cells

Solar Energy Materials and Solar Cells, 2016
AbstractResearch and development of silicon heterojunction (SHJ) solar cells has seen a marked increase since the recent expiry of core patents describing SHJ technology. SHJ solar cells are expected to offer various cost benefits compared to conventional crystalline silicon solar cells.

Silicon Heterojunction Microcells

ACS Applied Materials & Interfaces, 2021
We report the design, fabrication, and characterization of silicon heterojunction microcells, a new type of photovoltaic cell that leverages high-efficiency bulk wafers in a microscale form factor, while also addressing the challenge of passivating microcell sidewalls to mitigate carrier recombination. We present synthesis methods exploiting either dry

Characterization of silicon heterojunctions for solar cells [PDF]

Nanoscale Research Letters, 2011
AbstractConductive-probe atomic force microscopy (CP-AFM) measurements reveal the existence of a conductive channel at the interface between p-type hydrogenated amorphous silicon (a-Si:H) and n-type crystalline silicon (c-Si) as well as at the interface between n-type a-Si:H and p-type c-Si.

On the amorphous silicon on crystalline silicon heterojunctions [PDF]

Revue de Physique Appliquée, 1981
Accurate analysis and reinterpretation of recent results of a-Si heterojunctions have removed inconsistency of spectral and electrical measurements. Results of Schottky barriers and Mott-Schottky dispersion are discussed.

Surface texturisation for the reduction of light reflection in ZnO/Si heterojunction

International Journal of Sustainable Energy, 2022
In this paper, the impact of pyramidal texture on a silicon substrate in ZnO/p-Si heterojunction was investigated. The texturisation of p-type silicon (100) substrate was obtained using the KOH anisotropic wet chemical etching method for different ...
