| 20100179469 | Organic Light Emitting Diode Phototherapy Lighting System - A lighting system includes a plurality of organic light emitting diode (OLED) devices. By selecting the plurality of OLED devices, or by selectively controlling the plurality of OLED devices, the color characteristics of the lighting system can be tuned. The lifespan of the lighting system can be improved. | 07-15-2010 |
| 20100132782 | ORGANIC PHOTOVOLTAIC DEVICES COMPRISING FULLERENES AND DERIVATIVES THEREOF - Photovoltaic cells comprising an active layer comprising, as p-type material, conjugated polymers such as polythiophene and regioregular polythiophene, and as n-type material at least one fullerene derivative. The fullerene derivative can be C60, C70, or C84. The fullerene also can be functionalized with indene groups. Improved efficiency can be achieved. | 06-03-2010 |
| 20090023842 | PORPHYRIN AND CONDUCTIVE POLYMER COMPOSITIONS FOR USE IN SOLID-STATE ELECTRONIC DEVICES - Compositions comprising porphyrinic macrocycles and conjugated polymers such as polythiophene for use in organic electronic devices including solar cells are presented. Covalent linkage of a porphyrinic macrocycle to a polymer allows tuning of electronic and spectroscopic properties of conjugated polymers and can improve the heat stability of the system relative to a blended comparison. A composition comprising: at least one polymer comprising at least one porphyrinic macrocycle covalently linked to at least one conjugated polymer, wherein the porphyrinic macrocycle is metal-free is also presented. Inks can be formulated. Methods of making are provided. | 01-22-2009 |
