Perovskite-Silicon Solar: Record Voltage

• Discover how Fraunhofer Institute for Solar Energy Systems ISE achieved a record open circuit voltage of >2.8 V in their perovskite-based triple-junction solar cell. Understand how optimizations in interlayers and gas quenching methods enabled this success and how this could lead to more efficient solar energy generation in the future.

A research team at the Fraunhofer Institute for Solar Energy Systems ISE has developed a promising perovskite-based triple-junction solar cell with an open circuit voltage of >2.8 V, a record value for this type of cell. This achievement was made possible through a gas quenching method for deposition of the top perovskite layer, as well as optimization of interlayers between perovskite subcells. This opens up huge untapped potential for combining perovskite and silicon to generate electricity. The team's success suggests that the cell has excellent material properties for electricity generation, and that the fundamental aspects needed for a very efficient solar cell are in place. These findings could be instrumental in advancing the concept of triple-junction solar cells in the future.
