According to relevant media reports, a research team from the Helmholtz Center in Berlin, Germany, and Humboldt University has jointly developed a new type of perovskite stacked battery. This battery has broken the world record for similar batteries with a photoelectric conversion efficiency of 24.6%.

 



In the solar cell family, in addition to silicon-based solar cells, there are also thin-film solar cells such as copper, indium, gallium, and selenium based thin-film solar cells (CIGS cells). The production of this type of battery requires very little energy and materials, so its impact on the environment is also minimal.

The team combined CIGS cells as the bottom with perovskite based top cells to develop a new stacked solar cell. By optimizing the contact layer between the top and bottom batteries, they increased the energy efficiency of the new battery to 24.6%. This energy efficiency value has been certified as a new world record by the Fraunhofer Institute for Solar Energy Systems in Germany.

The team also developed CIGS sub cells and contact layers, and used high-performance cluster systems. This system can accurately deposit perovskite and contact layers in a vacuum environment, providing a solid guarantee for the high efficiency of new batteries. They believe that in the future, the photovoltaic conversion efficiency of new perovskite stacked solar cells is expected to exceed 30%.
