Hybrid porous silicon/silver nanostructures for the development of enhanced photovoltaic devices

Si-based metal–insulator–semiconductor (MIS) Schottky junction solar cells with the basic structure Al/Si/TiO2/Au were fabricated. This structure was modified by the addition of nanostructured porous silicon (nanoPS) layers and silver nanoparticles (AgNPs), resulting in devices with the following structures: Al/Si/nanoPS/TiO2/Au and Al/Si/nanoPS+AgNPs/TiO2/Au. The key performance parameters of the three MIS Schottky junction solar cells were...
