As screen printed contacts are the predominant metallisation technique in industrial production of Si solar cells, a better understanding of their properties is necessary. In this work, we show that high-quality cross-sectional samples can be prepared, who ...
Dye-sensitized nanocrystalline solar cells (DSC) have received considerable attention as a cost-effective alternative to conventional solar cells. One of the main factors that has hampered widespread practical use of DSC is the poor thermostability encount ...
The case for thin-film silicon as one of the main future options for cost-effective photovoltaic solar cells is outlined. The limitations of present amorphous silicon (a-Si:H) solar cells are briefly mentioned. Hydrogenated microcrystalline silicon (μc-Si: ...
Intrinsic microcrystalline silicon opens up new ways for silicon thin-film multi-junction solar cells, the most promising being the "micromorph" tandem concept. The microstructure of entirely microcrystalline p-i-n solar cells is investigated by transmissi ...
Temperature and electric field dependencies of mobility and concentration transients of electrons and holes using modified charge extraction by the linearly increasing voltage (CELIV) method in slightly doped n-type, p-type and undoped microcrystalline sil ...
Hydrogenated microcrystalline silicon i-layers were deposited with a fixed silane concentration on various substrates and incorporated into n-i-p solar cells. 'Average crystallinity' and detailed microstructure of layers and devices were evaluated by X-ray ...
In microcrystalline hydrogenated silicon (μc-Si:H), the drift mobility dependencies of holes on electric field and temperature have been measured by using a method of equilibrium charge extraction by linearly increasing voltage. At room temperature the est ...
The photoelectrochem. properties of ZnO electrodes were studied in the near-UV region. Studies were carried out on electrodes with different morphologies, porosities, and film thicknesses to probe the influence of these parameters on the photoelectrochem. ...
The aim of this communication is to show that it is possible to extend the model of the electronic transport developed for amorphous silicon (a-Si:H) to microcrystalline silicon (μc-Si:H). By describing the electronic transport with the μ0τR products (mobi ...
We report the observation of confined modes in the mixed photon/exciton-like branches of exciton-polaritons propagating along the growth axis of a 700 nm-thick GaN film, deposited by Molecular Beam Epitaxy on bulk GaN substrates. The energies of the confin ...
