摘要： A high efficiency solar cell and method for the same is provided to improve contact resistance of an ohmic electrode by forming the ohmic to be inclined less than 45 degrees. An inclined side is formed by using dry or the wet etching in forming an ohmic layer(450) which is formed on the inclined side by less than 45 degrees. An incident light(L) which is projected to the side of the top ohmic electrode is reflected at the ohmic electrode by over 45 degrees. The incident is projected inside the solar cell through an anti-reflection layer(480). The contact width of contacting ohmic layer is larger than that of the rectangle ohmic electrode, so high efficiency of a photoelectric conversion rate is obtained.

摘要： A system and a method for identifying a visitor with a web service are provided to transfer a message between a server and a client without any message format conversion even if the system is operated in heterogeneous OSs(Operating System), and detect face feature of the visitor periodically on the network without making the visitor register a face image to a visitor database. A visitor database(630) stores a visitor face feature template including face feature of each visitor. A web service client(611) periodically obtains a visitor image output from a camera, detects a face image of the visitor from the obtained image, extracts the face feature from the detected face image, and transmits the extracted face feature to a web service server(620) by using a visitor authentication request message. The server extracts the face feature from the received message, and determines whether the visitor face feature template similar to the extracted face feature is found in the visitor database by using similarity between the visitor face feature templates with the extracted face feature. The server transfers a visitor authentication response message when the visitor face feature template similar to the extracted face feature is found.
