Abstract: The present invention relates to a solar cell having an edge collecting electrode and a solar cell module comprising the same, the solar cell being capable of preventing a cell crack phenomenon caused by an interconnector and improving an adhesive characteristic of the interconnector by dividing a planar area of the solar cell into a main area and an edge area and positioning the outermost contact point of the interconnector at a boundary between the main area and the edge area, and being capable of improving carrier collecting efficiency by arranging, in the edge area, the edge collecting electrode and the branched electrode which are physically separated from the interconnector.

Abstract: The present description relates to a frequency-based wake-up device and a sensor communication device using such the same. The present invention comprises: a RF signal to voltage converter for receiving a wireless signal including a first signal and a second signal and converting the frequency of the preamble to voltage to generate a driving voltage and provide the same; a decoder activated by the driving voltage and extracts ID information of the sensor communication device by decoding the second signal; and a signal processor that is activated by the driving voltage and compares the extracted ID information of the sensor communication device by the decoder with pre-stored ID information of a pre-determined sensor communication device and notifies of reception of a wake-up signal when the extracted ID information and the pre-stored ID information are the same.

Abstract: Disclosed is a capacitor for a semiconductor device, comprising: a lower electrode formed over a predetermined lower structure on a semiconductor substrate; an aluminum oxynitride film formed over the lower electrode and having a low leakage current characteristic; a yttrium oxynitride film formed over the aluminum oxynitride film and having a higher dielectric constant than the aluminum oxynitride film; and an upper electrode formed over the yttrium oxynitride film, and a manufacturing method thereof.

Abstract: A technique for reading speech mail or text E-mail stored in a computer by an external telephone uses an apparatus which includes: a text to speech converting service function, a speech sensing function, an E-mail managing function, and an E-mail down-loading function. The apparatus may use software which includes a program for calling the E-mail client of a computer by one of a public telephone, a cellular phone, and a portable computer having a speed phone capability, gaining access to the received E-mail, converting text E-mail into speech mail, and transmitting it to a receiver through a telephone line. Also, a computer periodically detects an E-mail server during the absence of a user and, when it is determined that there is received E-mail as a result of detecting the E-mail server, down-loads the E-mail and stores it in the computer. When urgent E-mail is received, the computer calls a receiver and informs him or her that urgent E-mail has arrived or transmits the urgent E-mail to the remote receiver.
