Germany's latest photovoltaic 402030 polymer batteryefficiency reaches 19.5%, a new record for polycrystalline silicon cells
Germany's Q-Cells has developed a photovoltaic 402030 polymer batterywith an efficiency of 19.5%. Q-Cells said that this research has been confirmed in the Fraunhofer independent calibration laboratory and has set a new record for polycrystalline silicon cells.
Peter Waver, deputy president of Q-Cells Technology R&D Department, said that the solar 402030 polymer batteryis based on the new Q.ANTUM concept of Q-Cells in recent years. We will continue to optimize the 402030 polymer batteryefficiency to reach more than 20%.
Backside metallization and passivation are performed on 180-micron-thick polysilicon wafers at the in-house laboratory at the Thalheim Research Center in Germany. According to the company, this is a new backside structure consisting of an insulating layer and local connections. This improves the photoelectric properties of solar cells, which is a significant improvement over previous technologies.
