CdS/CdTe Heterostructures for Applications in Ultra-Thin Solar Cells [PDF]

Materials, 2018
The preparation of ultra-thin semi-transparent solar cells with potential applications in windows or transparent roofs entails several challenges due to the very small thickness of the layers involved. In particular, problems related to undesired inter-diffusion or inhomogeneities originated by incomplete coverage of the growing surfaces must be ...

Ultra-Thin Films of CdS Doped with Silver: Synthesis and Modification of Optical, Structural, and Morphological Properties by the Doping Concentration Effect

Coatings
Obtaining wide energy-gap semiconductor ultra-thin films is an important aspect for their application in sulfide-based solar cells. By reducing the optical losses associated with light reflection and exhibiting absorption edge shifts towards short wavelengths, these layers can optimize the amount of photons interacting with the active photovoltaic ...

Two-Dimensional Self-Organization of CdS Ultra Thin Films by Confined Electrochemical Atomic Layer Epitaxy Growth [PDF]

The Journal of Physical Chemistry C, 2006
We present a method that uses patterned self-assembled monolayers (SAMs) of alkanethiolates on silver as templates to fabricate ordered two-dimensional arrays of solid US nanoclusters. The US is grown by electrochemical atomic layer epitaxy inside sub-micrometric stripes of hexadecanthiol SAM fabricated by microcontact printing. US ultrathin films grow
