Amorphous Silicon/Crystalline Silicon Heterojunction Solar Cells [PDF]
, 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 ...

A silicon heterojunction transistor
Applied Physics Letters, 1979SIPOS (Semi-insulating polycrystalline silicon) which is used as a surface passivation layer for highly reliable silicon devices constitutes a good heterojunction for silicon. P- or B-doped SIPOS has been used as the emitter material of a heterojunction transistor with the base and collector of silicon. An npn SIPOS-Si heterojunction transistor showing

Polyaniline / silicon heterojunctions
Synthetic Metals, 1991Abstract The p-n and p-p polyaniline PAn/Si heterojunctions have been prepared and investigated. It is demonstrated experimentally that the p-n PAn/si heterojunction is a fine rectifying junction with obvious photoelectrical characteristics, and the barrier of the p-n PAn/Si heterojunction is mostly concentrated at the surface of Si.

Photovoltage spectra of silicon/porous silicon heterojunction
Solid State Communications, 1994Abstract The photovoltage spectroscopy of silicon/porous silicon hetero-junction has been studied, and proved to be a successful method to analyze the electronic structure of both silicon/porous silicon heterojuction and porous silicon. A series of excitation energy steps were observed at the photovoltage spectra of porous silicon. It is suggested to

Photodetection with heterojunctions of graphene and silicon
SPIE Proceedings, 2013The generation of e-h pairs in silicon by incident light is the underlying principle behind most silicon-based photodetection, imaging, photometry, spectroscopy and photovoltaic technologies. In this work, we show that graphene provides voltage-tunable ways in which the photogenerated carriers in Si can be captured.

Diamond/silicon heterojunction structures
Diamond and Related Materials, 1992Abstract Diamond/silicon heterojunctions (DSHJs) and related characteristics have been studied. Heterojunctions can be obtained by growing p-type diamond films (DFs) on p-type silicon substrates to form homotype (p-p) DSHJs; or by growing p-type diamond films on n-type silicon substrates to form heterotype (p-n) DSHJs via the route of chemical vapor ...

A Diamond Silicon Heterojunction Diode
MRS Proceedings, 1989ABSTRACTThin diamond films were grown on low resistivity p-type Si wafers by microwave plasma assisted chemical vapor deposition. Using gold contacts, diode-like behavior was observed and forward bias current densities in excess of 5 A/cm2 were obtained. Reverse bias current densities were as low as 5 mA/cm2.

The three topics presented in this thesis all concern silicon heterojunction growth and device applications. We developed growth techniques for two relatively immature material systems, silicon/calciumfluoride (Si/CaF2) and silicon/silicon-carbon (Si/Si1-yCy), and fabricated devices which take the mature silicon/silicon dioxides (Si/SiO2) material ...

SIPOS Heterojunction contacts to silicon
1984 International Electron Devices Meeting, 1984Using SIPOS films (SiO x , x oe , by at least a factor of fifty when compared to a conventional emitter structure with a metallic contact. Previous attempts to explain this J oe reduction have focused on the bulk properties of the SIPOS films. Experimental results of this study which attained J oe values of 2 × 10-14A/cm2, suggest that an interfacial ...
