Photosensitivity spectrum of long diodes with varied band base under the realization of galvanomagnetorecombination effect

Abdelali M., Belal T., Medjadi D. , Zair R. — 2012-01-24T10:16:23Z

In this paper, the results of investigation of the spectral characteristics of the injectional
photodiodes with a varied base are presented under the condition of the existence of
Galvanomagnetorecombination (GMR) effect. This is the redistribution majority and minority charge
carriers within the volume of the semiconductors in the presence of the magnetic field and the
formation of non equilibrium electron hole plasma (...)

Dielectric properties of flash - evapored CuInSe2 photovoltaic thin films

Abdelali M., Belal T., Linares C., Zair R. — 2012-01-24T10:13:45Z

In this paper, we have analyzed the dielectric functions of CuInSe2 photovoltaic thin
films, ε = ε1 + iε2 .Thus we have obtained the dispersion spectra corresponding to ε1 (λ ) and
ε2 (λ ) from spectrophotometry measurements for different thicknesses of thin films.

Optical properties of flash - evapored CuInSe2 thin films

Abdelali M., Belal T., Guastavino F., Linares C., Zair R. — 2007-01-13T09:39:09Z

CuInSeè thin films (CIS) are fabricated by flash evaporation in vaccum from a single source. Their optical properties are investigated by spectrophotometry in the range 0.3-2.5 pm. The interpretation ofthese results are based on the Mue//er numerical method ofresolution ofnonlinear equations. We have determined the optical constants. The optical energies gap are deduced for different thicknesses of thin films.
