Abstract: Cobalt polypyridine complexes are interesting alternative redox mediators for large scale manufacturing of dye-sensitized solar cells (DSCs) since they are less aggressive towards metal contacts and absorb less light than iodide/triiodide. Here we have examined the effect of steric properties of triphenylamine-based organic sensitizers and cobalt polypyridine redox mediators on the electron lifetime and overall device performance in DSCs. Matching the steric bulk of the dye and redox mediator was found to minimize recombination and mass transport problems in DSCs employing cobalt redox mediators. Recombination was efficiently slowed down by introducing insulating butoxyl chains on the dye, allowing the use of a cobalt redox mediator with a less steric bulk. The best efficiency of DSCs sensitized with a triphenylamine-based organic dye in combination with cobalt(II/III) tris(2,2?-bipyridyl) match the highest efficiencies obtained so far with iodide-free electrolytes, reaching a 6.

Abstract: A web server implements a call service, including call service data corresponding to a directory number of a user. The web server includes a first interface for communicating with a call processor that processes telephone calls in a telecommunications network. The processor communicates with a database that includes the call service data. The web server further includes a second interface for communicating with the user's computer via a packet switching network, the user computer including a display for displaying activation fields, which include a first activation indicator corresponding to the call service and a second activation indicator corresponding to a first feature of the call service. Each of the activation indicators enables selection of one of an ON and an OFF condition.

Abstract: A call forwarding service forwards calls placed to a subscriber's number to a forward-to number. Enabling an interface with the call forwarding service includes transmitting display data from a call forwarding service server through a packet switched data network to the subscriber's graphical user interface. At least a portion of the display data is displayed on a first screen of the graphical user interface, which includes a forward-to number field and at least one of multiple activation fields. The activation fields include a first activation indicator corresponding to the call forwarding service, a second activation indicator corresponding to the screening list and a third activation indicator corresponding to the schedule. Selection data is entered by the subscriber in response to the first screen, the selection data indicating one of an ON condition and an OFF condition corresponding to the at least one of the activation fields.

Abstract: A system, method and software are provided for implementing an adaptive and dynamic call center customer service delivery solution. In operation, a user interface (U/I) model is selected from a library of U/I models as the U/I model likely to elicit favorable customer responses and to achieve customer completion of the selected transaction. The active U/I model may be re-evaluated at each node of the selected transaction and a new model selected in response to a determination that the active U/I model is no longer preferred. One or more U/I models may be updated based on observed user responsiveness, the efficiency of past transactions as well as on other grounds.
