Query: Influence of Periodic Surface Nanopatterning Profiles on Series
  Resistance in Thin-Film Crystalline Silicon Heterojunction Solar Cells   In the frame of the development of thin crystalline silicon solar cell
technologies, surface nanopatterning of silicon is gaining importance. Its
impact on the material quality is, however, not yet fully controlled.We
investigate here the influence of surface nanotexturing on the series
resistance of a contacting scheme relevant for thin-film crystalline silicon
heterojunction solar cells. Two dimensional periodic nanotextures are
fabricated using a combination of nanoimprint lithography and either dry or wet
etching, while random pyramid texturing is used for benchmarking. We compare
these texturing techniques in terms of their effect on the series resistance of
a solar cell through a study of the sheet resistance (Rsh ) and contact
resistance (Rc) of its front layers, i.e., a sputtered transparent conductive
oxide and evaporated metal contacts. We have found by four-point probe and the
transfer length methods that dry-etched nanopatterns render the highest Rsh and
Rc values. Wet-etched nanopatterns, on the other hand, have less impact on Rc
and render Rsh similar to that obtained from the nontextured case.
