Pi-Conjugated Heavy Metal Polymers For Organic White Light Emitting Diodes

Invention SummaryOrganic light emitting diodes are primarily used in display devices and sometimes in lighting devices. Poor quality of white light emitted by these diodes and their complex fabrication methods may make them undesirable. A new polymer has been synthesized and characterized that emits a broad spectrum which appears white to human eyes....

Miniature Acoustic Energy Converter

Invention SummaryA number of devices have been developed that enable the generation of electricity by a two-stage conversion of heat to sound and sound into electricity. A thermoacoustic resonant system has been designed that generates sound from injected heat. A cavity coupled to the resonator provides positive feedback and sustains the acoustic oscillations....

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,...
