Structure and morphology evolution in mechanochemical processed CuInS2 powder

Non-vacuum mechanochemical route to the synthesis of Cu2SnS3 nano-ink for solar cell applications

“…The fragmented brittle particles tend to become obstructed by ductile particles. Fracture and cold welding produce a continuous exchange of matter between particles and ensure mixing of the various elements of the original powders [25]. After 12 h mechanochemical reaction, some large agglomerates were formed in the CTS samples due to their different solidities ( Fig.…”

Effects of the growth temperature on the properties of spray deposited CuInS2 thin films for photovoltaic applications

“…All the films have comparable absorbance in the visible spectral range and the absorbance decreases with the temperature increase. This can be explained by the slight decrease in the thickness of the films deposited at higher temperatures as result of the densification process, forming larger grains [31]. The absorbance significantly decreases in the IR spectral range (beneficial fact in the photovoltaic conversion), proving that these optical parameters are morphology-related, and could be corroborated with the multiple scattering on the small-sized grains that lead to a more efficient radiation trapping in UV and vis [32].…”

Properties of spray deposited nanocrystalline indium selenide thin films

“…All the films have comparable absorbance in the visible spectral range and initially the absorbance increases with substrate temperature up to 350°C decreases thereafter for further increase in temperature. This can be explained by the slight decrease in the thickness of the films deposited at higher temperatures as result of the densification process, forming larger grains [35,41]. The absorbance significantly decreases in the IR spectral range (beneficial fact in the photovoltaic conversion), proving that these optical parameters are morphology-related, and could be corroborated with the multiple scattering on the small-sized grains that lead to a more efficient radiation trapping in UV and Vis [42].…”
