| 20120097233 | PHOTOVOLTAIC DEVICE - A photovoltaic device is disclosed. The photovoltaic device includes a substrate, an anode, a cathode, two semiconducting layers, and an electron transporting layer. The first semiconducting layer comprises a first metallophthalocyanine. The second semiconducting layer includes a blend of a second metallophthalocyanine with an electron acceptor. The second semiconducting layer is located between the first semiconducting layer and the electron transporting layer. The first and second metallophthalocyanines have different valences. The complementary absorption profiles of these layers result in a device having greater absorption and efficiency than expected, without the need for a recombination layer or the need to match current between layers. | 04-26-2012 |
| 20120097249 | PHOTOVOLTAIC DEVICE - A photovoltaic device is disclosed. The photovoltaic device includes a substrate, an anode, a cathode, and a semiconducting bilayer. The bilayer is composed of a first continuous sublayer and a second continuous sublayer. The first sublayer includes a first polymorph of a metallophthalocyanine. The second sublayer includes a second polymorph of the same metallophthalocyanine. The complementary absorption profiles of the polymorphs result in a device having greater absorption and efficiency, improving performace of the photovoltaic device. | 04-26-2012 |
| 20120097250 | PHOTOVOLTAIC DEVICE - A photovoltaic device is disclosed. The photovoltaic device includes a substrate, an anode, a cathode, and two semiconducting layers. The first semiconducting layer comprises a phthalocyanine. The second semiconducting layer includes a blend of a polythiophene with an electron acceptor. The complementary absorption profiles of these layers result in a device having greater absorption and efficiency. | 04-26-2012 |

| 20120059658 | METHODS AND APPARATUS FOR PERFORMING AN INTERNET SEARCH - Embodiments of the present invention relate to searching for content on the Internet. A user may supply a search query to a device, and the device may issue the search query to a plurality of search engines, including at least one general purpose search engine and at least one site-specific search engine. In this way, the user need not separately issue search queries to each of the plurality of search engines. | 03-08-2012 |
| 20120059810 | METHOD AND APPARATUS FOR PROCESSING SPOKEN SEARCH QUERIES - Some embodiments relate to a method of performing a search for content on the Internet, in which a user may speak a search query and speech recognition may be performed on the spoken query to generate a text search query to be provided to a plurality of search engines. This enables a user to speak the search query rather than having to type it, and also allows the user to provide the search query only once, rather than having to provide it separately to multiple different search engines. | 03-08-2012 |
| 20120059814 | METHODS AND APPARATUS FOR SELECTING A SEARCH ENGINE TO WHICH TO PROVIDE A SEARCH QUERY - Some embodiments relate to a method of performing a search for content on the Internet, in which a user may issue a search query, and the search engine or engines to which that query is provided may be determined dynamically based on any of a variety of factors. For example, in some embodiments, the search engine or engines to which the query is provided may be determined based on the content of the search query, this historical access patterns of the user that issued the query, or the historical access patterns of other users. | 03-08-2012 |
