Printing Screens Revisited
  Research continues on improving printed frontside silver conductor line efficiency.A simple Internet search will reveal the photovoltaic industry is working hard on higher aspect ratio frontside conductor grids as a route to greater solar cell efficiencies. This is because the conductors, typically screen-printed on a cell’s frontside, block sunlight from reaching the energy converting strata below, and the narrower they are, the less shadow they cast. However, as it is essential they...
