- performance of vacuum-prepared materials and non-vacuum-prepared materials is usually attributed to the sensitivity of the chalcopyrite semiconductor to external contaminants [29], to the dependency of its properties on the preparation method [30], and to the self-doping characteristics of the chalcopyrite
- evaporated in excess of 30 times, as it is typical for chalcopyrite materials [32][33][34]. All samples presented in this work were deposited for a period of 5 min and with a substrate rotation of 10 rpm, to improve the homogeneity of the samples. Under these conditions a nominal CIS growth rate of 6 ± 1 Å

- that are based on the chalcopyrite compound CuInSe2 (CISe) have been intensively studied [1]. The basic advantages of CuInSe2 as a light absorbing material are its high photovoltaic efficiency and the stability of its properties over time. Apparently, the conversion efficiency can be improved by the
- precursor solution route does not employ the highly toxic gaseous hydrogen selenide as a Se-source. However, suitable precursors are not always available for a desired functional material, but nevertheless there are already several reports on different single source molecular precursors for chalcopyrite
- structural properties can be thus obtained. The most intensive peak at 172 cm−1 results from the Γ1 chalcopyrite phonon mode (selenium anion vibration) [24]. This signal is commonly observed in CuInSe2 thin films and nanoparticles, and its intensity is associated with the crystalline quality [25][26][27]. A
