The world of group IV nanomaterials for applications in photovoltaics is vast and heterogeneous. It includes silicon and germanium quantum dots and nanowires (NWs) and their combinations; quantum wells; graphene and carbon nanotubes. Silicon and germanium nanoparticles are candidates in tunable band-gap absorbers in third-generation multijunction solar cells [1]; NWs exhibit remarkable scattering and are used to enhance the absorption well beyond the value of the corresponding bulk materials [2]; if fabricated in quantum dimensions, they combine a tunable band gap with electrical transport properties [3]; graphene
