| 20080303432 | Systems and methods for improving the qualities of polymer light-emitting electrochemical cells - A light-emitting device comprising a pair of electrodes, and an emitting polymer active layer between the pair of electrodes, and either a) an electron transport layer, b) a hole transport layer, or c) a low work function material layer, wherein said emitting polymer layer comprising a single phase combination of a light-emitting polymer and an ionic liquid, is provided. Such multilayered devices have increased stability at relatively high voltages, fast turn-on times, low operating voltage, high brightness and long lifetimes. | 12-11-2008 |
| 20080315187 | ENHANCING PERFORMANCE CHARACTERISTICS OF ORGANIC SEMICONDUCTING FILMS BY IMPROVED SOLUTION PROCESSING - Improved processing methods for enhanced properties of conjugated polymer films are disclosed, as well as the enhanced conjugated polymer films produced thereby. Addition of low molecular weight alkyl-containing molecules to solutions used to form conjugated polymer films leads to improved photoconductivity and improvements in other electronic properties. The enhanced conjugated polymer films can be used in a variety of electronic devices, such as solar cells and photodiodes. | 12-25-2008 |
| 20090101891 | Multi-layered bipolar field-effect transistor and method of manufacturing the same - Disclosed herein is a multi-layered bipolar field-effect transistor, including a gate electrode, a gate insulating layer, an electron transport layer, a hole transport layer, a source electrode, and a drain electrode, in which an intermediate separating layer is formed between the electron transport layer and the hole transport layer, and a method of manufacturing the same. The multi-layered bipolar field-effect transistor has advantages in that, since a P-channel and a N-channel are effectively separated, the electrical properties thereof, such as current ON/OFF ratio, electron mobility, hole mobility, and the like, are improved, and, since a device can be manufactured through a solution process without damaging layers, the processability thereof is improved. | 04-23-2009 |
| 20090108255 | Processing Additives for Fabricating Organic Photovoltaic Cells - Processing additives, as well as related compositions, photovoltaic cells, photovoltaic modules, and methods, are disclosed. | 04-30-2009 |
| 20090126779 | PHOTOVOLTAIC DEVICES IN TANDEM ARCHITECTURE - A tandem photovoltaic device includes a first cell and a second cell arranged in tandem. The first cell is configured to receive incident electromagnetic radiation and includes a first charge separating layer having a first semiconducting polymer adapted to create electric charge carriers generated by electromagnetic radiation. A second cell is configured to receive electromagnetic radiation passing out of the first cell in a light propagation path. The second cell includes a second charge separating layer having a second semiconducting polymer adapted to create electric charge carriers generated by electromagnetic radiation. A first titanium oxide layer is interposed between the first and second cells, wherein the first titanium oxide layer is substantially amorphous and has a general formula of TiOx where X being a number of 1 to 1.96. | 05-21-2009 |
