Figure 5From: Metal nanoparticle-enhanced photocurrent in GaAs photovoltaic structures with microtextured interfaces The spectra of photocurrent enhancement for Au/GaAs diode structures with surface microrelief of quasigrating type. The structures have Ag/PVP nanolayer (1) and Au nanowire deposition with different mean periods of grating-like microreliefs, 0.76 μm (2) and 1.9 μm (3).Back to article page
