Latest Patents

Ji Hye Gwak holds a patent for a solar cell that features a rear buffer layer and a method of manufacturing the same. This invention relates to a thin-film solar cell design that improves the way solar light is absorbed. Unlike traditional designs, where a buffer layer and a transparent electrode are placed on a light absorption layer, Gwak's invention positions these components beneath a CIGS face. This unique arrangement allows solar light to directly reach the light absorption layer without any obstacles. Additionally, the first electrode and the buffer layer are patterned in a saw-toothed structure, which reduces the distance that electrons or holes must travel to reach the electrode or buffer layer after absorbing light energy.
