Nanostructure Surfaces for Photovoltaic Cells
Photovoltaic (PV) cells are typically formed from semiconductor absorber layers. These absorber layers exhibit absorption of light with photon energy above their bandgap energy to generate electron-hole pairs. The absorber layers can also exhibit non-radiative recombination in the bulk of the absorber material. However, the absorber semiconductor...

Multijunction Solar Cell with Thin-Film Polycrystalline Low-Bandgap Bottom Cell
There is a need for solar cells with highly efficient light-to-electricity conversion and lower cost. Multijunction cells, which include multiple light-absorbing materials, each of which converts a given wavelength range of the solar spectrum, can be used to provide greater conversion efficiency than single-junction thin-film solar cells. However,...

Polymeric Mac-Imprint Stamp Materials for High-Density Defect-Free Patterning of Semiconductors
Metal-assisted chemical imprinting (Mac-Imprint) is a contact-based wet etching process that combines metal-assisted chemical etching (MACE) and nanoimprint lithography (NIL). Mac-Imprint processes have been used for semiconductor patterning with arbitrary and complex 3D micro- and nano-structures. While porous catalytic metal thin-films can be used...
