Fabrication and characterization of a nanostructured TiO2/In2S3-Sb2S3/CuSCN extremely thin absorber (eta) solar cell

Modeling and characterization of extremely thin absorber (eta) solar cells based on ZnO nanowires.

Extremely thin absorber (eta)-solar cells based on ZnO nanowires sensitized with a thin layer of CdSe have been prepared, using CuSCN as hole transporting material. Samples with significantly different photovoltaic performance have been analyzed and a general model of their behavior was obtained. We have used impedance spectroscopy to model the device discriminating the series resistance, the r...

Selective Solar Absorber Materials: Nanostructured Surfaces

Current solar to thermal energy conversion technologies, including concentrated solar power (CSP) and solar water heaters (SWH) utilize absorber surfaces that collect incident solar radiation. However, these absorber surfaces emit thermal energy (at their temperature) in the infrared (IR) spectrum, resulting in decreased overall efficiency for solar-to-thermal conversion. Selective absorber sur...

Porous Silicon for Thin Solar Cell Fabrication

Fabrication and characterization of nanostructured ZnO thin film microdevices by scanning electrochemical cell microscopy.

Scanning electrochemical cell microscopy (SECCM) was proven to be a prospective microfabrication method for the in situ synthesis and multiscale assembly of functional nanomaterials into microdevices. Nanostructured ZnO thin film was synthesized and assembled by SECCM, which has excellent electrochemical capacitance and electronic I-V properties.

Synthesis and Characterization of Nanostructured Thin Films of (CdS)0.6 Se0.4 for Solar Cell

The high quality thin films of (CdS)0.6 Se0.4 have been synthesized using thermal evaporation technique onto precleaned rotating amorphous glass substrate at room temperature. The films were characterized by X-Ray Diffractometer, Scanning Electron Microscopy, Atomic Force Microscopy and UV-VIS Spectrophotometer. The XRD spectrum illustrates that the films are polycrystalline having hexagonal st...
