Ultra-thin metal electrodes help improve solar cell efficiency

      Currently, silicon is the standard material for solar cells, and perovskite and silicon are independently used as semiconductor materials for solar panels. For a long time, the efficiency target of perovskite/silicon tandem solar cells is 30%. But scientists believe that in the process of creating more efficient solar cells, current research is approaching the limits of the technology.


      Now, researchers from the Department of Materials Science and Engineering at Pennsylvania State University claim that the new ultra-thin metal electrode they have developed enables researchers to create highly efficient translucent peroxide solar cells that can be combined with traditional silicon cells to greatly improve the two The performance of each device. This research represents a step towards the development of fully transparent solar cells.


      The peroxide solar cell consists of five layers, and the other cell layers are damaged or degraded by the material tested as the transparent electrode. In laboratory tests, the solar cells with gold electrodes made by the researchers are stable and maintain high efficiency for a period of time. Researchers believe that this breakthrough in the design of tandem cell architecture based on transparent electrodes can provide an effective way for the transition to peroxide and tandem solar cells.
