Excitonic luminescence in CuInSe2

Applied Physics Letters, 1998
Band-edge luminescence of CuInSe2 single crystals was studied in the temperature region between 2 and 300 K. Sharp emission lines were attributed to the decay of free and bound excitons and their phonon replica. Accurate analysis of the peak position revealed values of 4.4 meV and 1.044 eV for the binding energy of the free exciton and the band gap at ...

Spray pyrolysis of CuInSe2

Solar Cells, 1986
Abstract Spray pyrolysis is a low-cost method of depositing thin films and is an economically attractive alternative to the vacuum deposition methods that have been used to produce stable CuInSe 2 -based solar cells. Thermodynamic studies have shown that the preferred deposit from an aqueous solution of CuCl 2 , InCl 3 and N,N-dimethylselenourea is ...

CuInSe2 for photovoltaic applications

Journal of Applied Physics, 1991
The properties and most successful methods for producing CuInSe2 films for solar-cell applications are reviewed and the production, analysis, and performance of photovoltaic devices based on CuInSe2 are discussed. The most successful methods for depositing thin CuInSe2 films for high-efficiency solar cells are three-source elemental evaporation and ...

EBIC analysis of CuInSe2 devices

Solar Cells, 1988
Abstract This paper describes the electron-beam-induced-current (EBIC) technique and its application to the characterization of CuInSe 2 thin film solar cells. The collected current generated by a scannig electron microscope electron beam can be used to determine spatial non-uniformities, localized defects, p-n junctions, minority carrier lifetimes ...

Deposition and characterization of CuInSe2

Renewable Energy, 1995
Abstract Polycrystalline CuInSe 2 thin film solar cells were prepared by two methods: three-source evaporation and co-electrodeposition from a single bath. Structural and compositional characterization was carried out by X-ray diffraction, energy dispersive X-ray spectroscopy (EDS), scanning electron microscopy (SEM) and transmission electron ...

Features of Bridgman-grown CuInSe2

Thin Solid Films, 2003
Abstract Using a one-ampoule method, ingots of CuInSe 2 were grown by the vertical Bridgman technique with specific nonstoichiometric proportions of the starting elements copper, indium and selenium. With stoichiometry or an excess of selenium, the ingots were p-type.

Transport properties of CuInSe2

Solar Cells, 1986
Abstract The electrical and thermal properties of CuInSe2 single crystals have been reviewed and in some cases, taking into account recently reported experimental values for the transport parameters, earlier results have been re-examined. Based on defect chemistry considerations and the formation energy of the predominant electrically active ...

Characterization of CuInSe2 single crystal

Physica B: Condensed Matter, 2007
Abstract High quality CuInSe2 (CIS) single crystals grown by the vertical Bridgman method. The electrical conductivity, Hall coefficient and thermoelectric power were measured as a function of temperature. The energy gap was found 1.04 eV. The crystals were characterized structurally by X-ray diffraction and compositionally by microprobe analyses ...

Neka svojstva CuInSe2

1984
Optička i električna svojstva poluvodičkog spoja CuInSe2 prikazana su u kao mogućnost korištenja tog spoja kao kandidata za nove solarne ćelije. To se posebno odnosi na moguću tehnologiju tankog filma zbog velikog koeficijenta apsorpcije, dobre stabilnosti i relativno velike efikasnosti pretvorbe sunčeve energije u električnu (cca 8%).

Flash evaporation of CuInSe2 films

Solar Energy Materials, 1988
Abstract Stoichiometric CuInSe2 films were prepared by flash evaporation on Mo or glass substrates. Structural characterization was carried out by microprobe, X-ray, scanning and transmission microscopy studies. These indicated the presence of the chalcopyrite phase, nearly stoichiometric composition, and that the deposits were relatively uniform ...
