Periodic nano/micro-hole array silicon solar cell. [PDF]
Nanoscale Res Lett, 2014 Abstract In this study, we applied a metal catalyst etching method to fabricate a nano/microhole array on a Si substrate for application in solar cells. In addition, the surface of an undesigned area was etched because of the attachment of metal nanoparticles that is dissociated in a solution.
