Optimized Nanophotonics for Thin-film Photovoltaic Cells

Invention SummaryThis novel design technique employs nanophotonic principles to create optimized light trapping structures in thin-film photovoltaic cells, in contrast to current “trial-and-error” nanophotonic designs. Randomly textured surfaces are applied on the top surface of the thin layers (several microns thick) of active PV cell materials....

Significantly Increasing Efficiency of Dye-Sensitized Solar Cells Using Nanostructured ZnO Electrodes

Invention Summary: Dye-sensitized solar cells (DSSCs) have received considerable attention as a cost-effective alternative to conventional solar cells. However, a major efficiency limiting factor in current nanoparticle-based DSSCs is the trap-limited diffusion transport mechanism of electrons, a slow mechanism that limits the device efficiency,...
