Effect of polymer layer deposition and annealing on photovoltaic properties of CuInS2/polymer structures; pp. 18–23 [PDF]

Proceedings of the Estonian Academy of Sciences, 2009
The effect of deposition of various polymer layers and annealing in the air at different temperatures on the surface photovoltage of CuInS2 photoabsorber films was studied. After polymer layer deposition onto the polycrystalline CuInS2 surface, roughness

Enhanced Light Absorption and Efficient Carrier Collection in MoS₂ Monolayers on Au Nanopillars

Nanomaterials, 2022
We fabricated hybrid nanostructures consisting of MoS2 monolayers and Au nanopillar (Au-NP) arrays. The surface morphology and Raman spectra showed that the MoS2 flakes transferred onto the Au-NPs were very flat and nonstrained.
