In the present paper, we report on thin-film microcrystalline silicon solar cells grown at high deposition rates on back-reflectors with optimized light-scattering capabilities. A single-junction solar cell with a conversion efficiency of η = 7.8% (2 μm th ...
A numerical two dimensional model to calculate the deposition uniformity over the whole electrode surface in large area rectangular plasma enhanced chemical vapour deposition reactors is presented. In this model, the three dimensional mass and species cont ...
The low energy part of proton induced SBD spectra have higher number of counts than expected from p+Si reactions. This is the case for all proton incident angles but the effect increases when approaching grazing angles. The effect is shown to be mainly due ...
A detailed study of the nucleation and growth of Cu on Ni(100) as a function of substrate temperature and deposition rate by variable temperature STM is reported. By the quantitative analysis of the saturation island density as a function of temperature an ...
a-Si:H i-layers were deposited at different substrate temperatures and plasma excitation frequencies, while the other deposition parameters were kept constant. These layers were characterised by measuring the intrinsic mechanical stress and the defect dens ...
The cavity ring-down technique is applied to an industrial-scale radio-frequency (rf) plasma reactor for the measurement of the density and spatial profile of negative ions in pure oxygen and hydrogen rf plasmas, and for the detection of nanometric particl ...
Designing plasma-enhanced chemical vapour deposition (PECVD) reactors to coat large-area glass plates (similar to1 m(2)) for flat panel display or solar cell manufacturing raises challenging issues in physics and chemistry as well as mechanical, thermal, a ...
Sn and Pt films were laser deposited on a quartz plate or C membrane supports by using light-induced thermal dissocn. and photodissocn. of SnMe4 and bis(hexafluoroacetylacetonato)platinum, resp. An Ar laser (l = 514.5, 455.5, 257.3 nm) and a Hg lamp (l = 2 ...
Laser direct writing of metal lines from solid metalorg. films coated on surfaces has been studied in three systems. Copper deposition from Cu(HCOO)2.2H2O was carried out at higher writing speeds than previously attained. Direct writing of iridium lines fr ...
Energy deposition rates in various materials irradiated in a large 60Co facility have been measured using both CaF2 and LiF TLDs. Since the relationship between energy deposited in the TLD and that deposited in the surrounding medium (1/f factor) was diffe ...
