A team of Swiss scientists has published a report in the esteemed journal Nature, revealing the development of a novel "sandwich"-structured solar cell. This innovative design combines perovskite and silicon materials, with a silicon-based bottom layer and perovskite thin films deposited on both the middle and top layers. The result? An impressive photoelectric conversion efficiency of 30.02%, significantly outperforming the previous record of 27.1%. To overcome challenges such as insufficient voltage in the top cell and weak current in the middle cell, the research team introduced specialized molecules and employed a three-step deposition process, marking a significant advancement in solar cell technology.
