Abstract: Solar cell including a substrate with first p-n-junction, separating the substrate into front portion having first doping and rear portion having second doping, being located close to front surface of substrate. A front layer having a p-n-junction, separating the front layer into front portion having first doping and rear portion having second doping. At least one first electric contact provided on front side of the solar cell electrically connected to front portion of the front layer, and second electric contact provided on rear side of solar cell electrically connected to a contact point provided on front side of the solar cell. Contact point is placed on a bottom surface of a groove open to front side of the cell and extending to rear portion of substrate, and an electrical connection between the second electric contact and the contact point is provided by the rear portion.

Abstract: A computer-implemented method for incorporating advertisement information into a video is disclosed. The method may include receiving a request for a modified video and receiving at least one parameter for determining advertisement information to be included in the modified video. Based on the received parameter, the method may select the advertisement information to be included in the modified video. The method may also include determining an advertisement area in a video for the advertisement information to be located, and generating the modified video by integrating the advertisement information into the advertisement area in the video. Further, the method may include sending the modified video to one or more devices.
