Trina Solar Limited has submitted a patent application for a solar cell and its manufacturing method, as well as for photovoltaic modules, aimed at enhancing the efficiency of photovoltaic power generation. According to information from the National Intellectual Property Administration, the patent, titled “3364. Solar Cell and Its Manufacturing Method, Photovoltaic Module,” was published under the application number CN119855285A, with the application date recorded as January 2025.
The patent summary indicates that the application pertains to a solar cell and its preparation method, which includes forming a first intrinsic amorphous silicon layer and a mask layer on the first surface of a substrate, creating grooves in the mask layer. Subsequently, a first doped semiconductor thin film layer and a first protective film layer are formed on the side of the mask layer that is away from the substrate. This arrangement ensures the first doped semiconductor thin film layer covers both the mask layer and the exposed areas of the first intrinsic amorphous silicon layer, while the first protective film layer covers the first doped semiconductor thin film layer.
Afterward, the mask layer and the first protective film layer, along with the first doped semiconductor thin film layer located on the side of the mask layer away from the substrate, are removed to yield the first doped semiconductor layer and a protective sub-part. The method continues with the formation of a second doped semiconductor thin film layer, which covers the protective sub-part and the uncoated portions of the first intrinsic amorphous silicon layer. Finally, the protective sub-part and the second doped semiconductor thin film layer away from the substrate are removed, resulting in the second doped semiconductor layer.
