Plasmonically Enhanced Thin-Film Amorphous Silicon Solar Cells

Sonsalla T., Louisiana Tech University, US

Hydrogenated amorphous silicon (a-Si:H) can absorb the visible part of the solar spectrum better than crystalline silicon. For this reason, a-Si:H solar cells can be much thinner than crystalline silicon solar cells. Thinner cells reduce [...]

Light Trapping in Solar Cells Using Nanostructured Reflectors: A Responsivity-Based Model Applied to Waveguide Mode Matching

Shahriad T., Shepard S.R., Louisiana Tech University, US

Although theoretically predicted that periodic photonic nanostructures can outperform the pseudo random structures in light trapping in solar cells, still the disputation regarding this topic is at the top. To enlighten the world about the [...]

Improved Nanophotonics Simulation Tools for Light-Trapping in Photovoltaics

Shepard S., Rubaiat F., Louisiana Tech University, US

Models used in the field of nanoparticle enhanced light-trapping have a wide range of complexity. Often one simply calculates how much power is absorbed in a particular region e.g., a layer of silicon withing a [...]

Periodic and Psuedo-Random Back-Reflector Nanoparticle Enhanced Light-Trapping in a Silicon Photovoltaic

Shepard S., Patel L., Rubaiat F., Louisiana Tech University, US

We consider the light-trapping enhancement of a silicon photovoltaic with conductive nanoparticles of various shapes, sizes and spacing as top-reflectors; used in conjunction with a periodic and a pseudo-random back-reflectors. The nanoparticles in the top-reflector [...]

Plasmonic Enhanced Light Trapping in a P3HT Photovoltaic

Shepard S., BakshiGupta D., St. Luce G., Louisiana Tech University, US

We consider the enhancement of an organic (P3HT) photovoltaic with conductive nanoparticles of various shapes, sizes and spacing as top-reflectors; used in conjunction with a periodic and a pseudo-random back-reflector. The surface for the pseudo-random [...]

A New Class of Nonlinear Light Trapping for Photovoltaic Systems

Shepard S., Louisiana Tech University, US

Light trapping is a useful way of enhancing photovoltaic conversion via any means by which light not converted to electricity in a photovoltaic (PV) in one pass through its PN junction, is given another opportunity [...]
