Contact Formation on P-doped Si by Screen-printing Pure Ag Pastes for Bifacial N-type Si Solar Cells
n-type solar cell concepts increasingly utilize emitter formation by diffusion from boron doped sources. Combining the advantage of n-type silicon material and bifacial cell architecture enables high-efficiency and versatile photovoltaics. In case of boron emitters, it was standard until now to form a metal-semiconductor contact by screenprinting Al containing Ag pastes. Instead of utilizing Al...
I n t r o d u c t i o n : The study of Ag isotopic compositions is of particular interest because of the extinct radionuclide Pd, which decays to Ag with a half-life of 6.5 Myrs. This chronometer has been successfully applied to unravel formation and differentiation processes of iron meteorites [1-3]. Compared to the early measurements by TIMS, the use of multi-collector inductively coupled pla...
the Sol–gel nanocomposite coatings have been investigated for copper metal as a potential replacement for the hazardous and banned hexavalent chromate conversion coatings. TiO2–CdO nanocomposite thin films were deposited on copper using the sol–gel method. The sol-gel coatings were prepared using a sol obtained by the hydrolysis and condensation of tetra-o-butyl titanate. They were doped with c...
