A study of the creation and characterization of nitrogen doped CuInSe2 (CIS:N), as a potential improved back contact material for CdTe and Cu(IN_xGA_1-x)Se2 photovoltaic cells
Nitrogen is incorporated into CuInSe2 (CIS), and other related materials, using a scalable, commonly used, technique. The growth characteristics, film morphology and electronic properties of these N doped materials, as it is affected by nitrogen, are studied, both in films grown with nitrogen, and …

Growth of epitaxial nanoscale columnar copper indium diselinide thin films by introduction of sodium flouride during growth
The effect of NaF on the growth of CuInSe2 (CIS) epitaxial thin films by a hybrid sputtering and evaporation method was studied. Low levels of NaF deposition during interruptions of epitaxial growth reduced surface roughness. Larger amounts of NaF resulted in columnar epitaxial films with <112> …

How visual representations affect undergraduate students’ use and understanding of engineering concepts during problem solving
… improving the efficiency of solar cells that use CuInSe2 (CIS) and Cu(In,Ga)Se2 (CIGS) as the absorber layer, which are inexpensive but limited due to a variety of defects. Understanding which elements are involved in charge capture and recombination would contribute to the literature by providing …

Impact of secondary barriers on CuIn1-xGaxSE2 solar-cell operation
Thin-film solar cells based on CuInSe2 (CIS) absorber with a band gap of Eg = 1.0 eV and also based on CuIn1-xGaxSe2 (CIGS) alloy absorbers with a band-gap range of Eg = 1.0 - 1.67 eV are investigated in this work. Intermediate "buffer" semiconductor layers in p-n junctions of CIGS solar cells …

Optical Modeling of Solar Cells
… in the work are Copper-Indium-Diselenide (CuInSe2) and Copper-Indium-Gallium-Diselenide (CIGS, CuInGaSe2).</p><p> The analysis of CuInSe2 and CuInGaSe2 showed that maximum current is produced when Indium – doped tin oxide (ITO) is used as TCO. The use of ITO as TCO results in highest short …

Physical and optoelectronic properties of copper silver indium diselenide thin films
… engineering. The effects of alloying Ag with CuInSe2 on the physical properties were shown. The addition of Ag appears to improve the structural quality of the films. This was seen by a reduction in the full-width-at-half-maximum of the luminescence peaks, a reduction in the number of optical …
