The invention relates to solution-processable, p-type, low-optical gap oligothiophene compounds for use in solar cell application, comprising at least one thiophene-containing group, at least one electron-withdrawing dicyanovinyl or tricyanovinyl group, and at least one electron-donating diphenylaminofluorenyl or N-alkylcarbazole group. 1. A compound for use in solar cell application having a structure of Formula V: This application is a divisional of U.S. patent application Ser. No. 13/930,681, filed Jun. 28, 2013, which is a non-provisional filing based on U.S. Provisional Patent Application Ser. No. 61/690,572, filed on Jun. 29, 2012, both of which are incorporated herein by reference.The invention relates to a synthetic compound for solar cell applications. Particularly but not exclusively, the invention also relates to an oligothiophene compound for solar cell applications.Fossil fuels are still one of the major energy sources nowadays. Example of fossil fuels such as coal, petroleum and natural gas are non-renewable natural resources which take thousands of years to form, and are costly to harvest. In addition, combustion of the fossil fuels generates large amount of carbon dioxide as well as undesirable air pollutants. To resolve this, clean and renewable energy resources such as solar energy which can be directly captured and converted to electrical energy by solar cells have been extensively researched and investigated. For example, photovoltaic (PV) technologies have been employed to fabricate different types of solar cells, such as crystalline silicon solar cells, amorphous silicon solar cells, dye-sensitized solar cells, copper indium gallium selenide (CIGS) solar cells and organic solar cells, etc.Among the solar cells manufactured by various PV technologies, organic solar cells are known to have the advantages of low-cost and high process flexibility in production. Particularly, organic solar cells such as bulk heterojunction (BHJ) photovoltaic (PV) ...

COMPARING TABLES WITH SEMANTIC VECTORS

A data processing system identifies a first topic for a first table, identifies a second topic for a second table, collects at least one first table attribute comprising at least one row name for the first table, and collects at least one second table attribute comprising at least one row name for the second table. The at least one first table attribute and the at least one second table attribute are placed in at least one semantic category. The at least one first table attribute is converted into at least one semantic vector for the first table, and the at least one second table attribute is converted into at least one semantic vector for the second table. The at least one semantic vector for the first table is compared with the at least one semantic vector for the second table to identify as related at least one row of the first table and at least one row of the second table. The at least one row of the first table and the at least one row of the second table are provided to a communication device with an identification as related. 1. A method comprising:identifying a first topic for a first table and identifying a second topic for a second table;collecting, by a data processing system, at least one first table attribute comprising at least one row name for the first table;collecting, by the data processing system, at least one second table attribute comprising at least one row name for the second table;placing, by the data processing system, the at least one first table attribute and the at least one second table attribute in at least one semantic category;converting, by the data processing system, the at least one first table attribute into at least one semantic vector for the first table and converting, by the data processing system, the at least one second table attribute into at least one semantic vector for the second table;comparing, by the data processing system, the at least one semantic vector for the first table with the at least one semantic vector for ...
