Latest Patents

One of Ji Sun Kim's latest patents is titled "Solar cell and method of manufacturing the same." This patent discloses a solar cell that includes a semiconductor substrate doped with a first conductive type impurity. A via hole is formed, passing from the first surface of the semiconductor substrate to the second surface, which faces the first surface. The first surface serves as the light-receiving surface. The solar cell also features upper and lower emitter layers, which are doped with a second conductive type impurity, and current collecting layers that are formed on the sidewalls of the via hole. These layers are doped with a higher concentration of the first conductive type impurity than that of the semiconductor substrate. Additionally, a contact electrode extends from the first surface to the second surface, filling the via hole, along with upper and lower electrodes that contact the emitter layers.

Another significant patent is the "Method for manufacturing solar cell." This method involves forming a dielectric film on a semiconductor substrate doped with a first conductive type impurity. The process includes exposing a high concentration doping region by partially removing the dielectric film and ion-implanting a second conductive type impurity into the front surface of the semiconductor substrate. This results in the formation of a high concentration doping layer corresponding to the high concentration doping region and a low concentration doping layer in the region where the dielectric film is present.
