Rapid growth of nanocrystalline CuInS2 thin films in alkaline medium at room temperature

The terahertz emission and photoelectron spectroscopy study of CuInS₂ thin films

“…CuInS 2 (CIS) with the band gap value of 1.5 eV and its high absorption coefficient of almost 10 5 cm −1 is representing an important class of the recently developed light absorbers for highly efficient and lowcost solar cells [1][2][3]. Recent studies have shown that CIS solar cell efficiency ranges from 10.2 to 12.3% [4][5].…”

Elemental Composition, Topography and Wettability of PbxSn1 - xS Thin Films

“…The wettability interferes with adhesion absorber surface [3] (and, in turn, with performance of the junction), which in turn inuences solar cell energy conversion eciency. Lokhande et al [4] and Roh et al [5] propose to use contact angle measurements as a diagnostic method to determine the quality of CuInS 2 absorbers without forming an actual solar cell. * corresponding author; e-mail: tashl@bspu.unibel.by…”

A new green synthesis method of CuInS2 and CuInSe2 nanoparticles and their integration into thin films

“…Various synthesis approaches have been recently developed specifically to produce sub-micron CIGS particles (Gurin 1998;Azad-Malik et al 1999;Czekelius et al 1999;Grisaru et al 2003;Castro et al 2004;Chun et al 2005;Roh et al 2005;Wei and Mu 2005;Dutta and Sharma 2006;Nakamura et al 2006). There are very few cases where monodispersed chalcopyrite nanoparticles with a diameter around 5 nm or less are obtained.…”
