Binaphthol Based Chromophores for the Fabrication of Blue Organic Light Emitting Diodes

An employment of binaphtyl core as a linking group of functional groups such as blue-fluorescent chromophore and electron transport unit. This compound has demonstrated several different functions in the application of organic light-emitting diode (OLED).

A novel technique for controlling the blend morphology in polymeric BHJ systems. When this technique is used to make the active layer in a photovoltaic device, photoconductivity and power conversion efficiency are enhanced. In addition, the thermal annealing step typically required in device manufacture can be eliminated, significantly reducing processing costs.

Enhanced Bulk Heterojunction Organic Solar Cells And Photodetectors

The high cost of inorganic silicon solar cells significantly limits their widespread application. Organic bulk heterojunction (BHJ) solar cells, on the other hand, use polymer blends that can be processed from solution and have the potential to yield cheap, flexible, and efficient solar cells.

Enhanced Tunnel Junction For Improved Performance In Cascaded Solar Cells

Solar energy created through photovoltaics is finding increasing interest as an alternative power source for domestic and industrial use. The amount of power generated by a solar cell array is limited to the amount of solar cell area. In order to increase power delivery, the efficiency of the solar cells has to be increased.  [read more]

Fullerene Composite Membranes for Direct Methonal Fuel Cell

Membranes fabricated from a proton-conducting host polymers and functionalized fullerenes that disperse within the host polymer, limit the amount of methanol crossover for the membrane.

Injection Lasers Fabricated from Semiconducting Polymers

A method for overcoming difficulties associated with the losses introduced by the metal electrodes and charge induced absorption by using an architecture known as the light-emitting field effect transistor (LEFET) configuration and to utilize injection-induced amplification of the “cut-off mode” to achieve gain narrowing and lasing.

Organic Photovoltaic Cells: Manufacturing and Design Improvements

Photovoltaic cells having active layers based on organic polymers are of interest as alternative sources of renewable electrical energy to the typical silicon-based cell. Such cells offer advantages such as low cost of fabrication in a variety of sizes, low weight and flexibility. [read more]

Polarization-Induced Tunnel Junction

A method to enable tunnel junctions in semiconductor systems that exhibit electrical polarization. The semiconductor material that exhibits strong piezoelectric and/or spontaneous electrical polarization that provides the tunnel junction comprises an interface of thin (<150nm), differing layers of (Al,In,Ga)N alloys. The tunnel junction may be between p-type and n-type semiconductor layers, or it may be between two n-type or p-type semiconductor layers.
