This research reveals the missing or often undisclosed experimental data on processing conditions of Cu(In,Ga)(S,Se)2 absorbers by the two-step sequential technique. Accordingly, by employing a one-variable-at-a-time approach- where each factor is ex

In this contribution, we report on the impact of ammonium sulfide ((NH4)(2)S-x) chemical treatments done at room temperature on the surface properties of Cu2ZnSnSe4 (CZTSe) thin film. The first approach is based on the immersion of the absorber layer

We report on the electrical, optical and physical properties of Cu2ZnSnSe4 solar cells using an absorber layer fabricated by selenization of sputtered Cu, Zn and Cu10Sn90 multilayers. A maximum active-area conversion efficiency of 10.4% under AM1.5G

One of the promising low cost and non-vacuum approaches for the fabrication of semiconductor CuInSe 2 and Cu(In,Ga)(S,Se) 2 thin film absorbers is the printing of precursor materials followed by a sintering/selenization process. The selenization proc

Cu 2 ZnGeSe 4 (CZGeSe) can be considered as a potential alternative for wide band gap thin film devices. In this work, CZGeSe thin films were deposited on Mo-coated soda lime glass substrates by sequential deposition of sputtered Cu, Zn and e-beam ev

We report on the electrical and physical properties of Cu2ZnSnSe4 (CZTSe) solar cells consisting of an absorber layer fabricated by selenization of sputtered Cu, Zn, Sn multilayers. Cross-section scanning electron microscopy images show that the poly

Selective epitaxial growth of GaAs on Ge is a prerequisite for the integration of GaAs and Ge in the sub-22 nm CMOS nodes. The problems encountered for epitaxial growth of GaAs on Ge are described and illustrated. Mainly the problem of anti-phase bou

It is well established that the addition of sodium (Na) to chalcopyrite or kesterite based solar cells markedly increases the solar cell performance. In this work, we explore the effect of Na and other alkali metals like potassium (K), rubidium, caes

We have fabricated and characterized Cu8SiS6 and Cu8SiSe6 thin film layers for optoelectronic applications. The layers were fabricated using a two step process by first evaporating a bilayer of Cu/Si on a Mo/glass substrate, followed by an anneal at
