Internal Microlens Arrays Enhancing Performance of Dye Sensitized Solar Cells
SUMMARY Existing solar cell devices only control light outside of the device as a top-layer coating or solar collector. This invention from Lehigh University incorporates the lenses within the device itself. The microlens arrays redistribute the light internally and increase the exposed surface area associated with the dye support. This method fo...

Facile, High Yield Synthesis and Purification of CdS Quantum Dots from Optimized Strains of S. maltophilia
SUMMARY A major barrier to the utilization of quantum dots (QDs) in commercial applications is the high cost associated with conventional chemical synthesis as well as the use of high temperatures and toxic solvents, thereby requiring specialized, expensive waste disposal procedures. Lehigh University has developed an optimized, bacterial-based syn...

Enhanced Light Emitting Diodes
SUMMARY InGaN based quantum wells (QWs) light-emitting diodes and laser diodes play an important role in solids sate lighting (SSL). As the InGaN QWs are coupled to surface plasmon (SP) mode of metallic film, the radiative recombincation rate can be enhanced due to the increased photon density of states near the SP frequency. Lehigh University h...
