Figure 4From: Metal nanoparticle-enhanced photocurrent in GaAs photovoltaic structures with microtextured interfaces The spectra of the short-circuit photocurrent for Au/GaAs diode structures. Structures have flat surface (1) and microtextured one (2 to 4), where (3) - for structures with introduced (PVP/Ag nanoparticles) layers, (4) - for structures with Au nanowires chemically deposited on the ridges of grating-like-type microrelief of GaAs surface.Back to article page
