23.7% Solar Cell: A New Monolith Perovskite-PERC
- New research from the Netherlands has led to the creation of a monolithic perovskite-PERC tandem solar cell with a tunnel recombination junction, achieving an efficiency of 23.7%. This technology is expected to be beneficial for scaling up to larger sizes.
Researchers from the Netherlands have designed a new monolithic perovskite-PERC tandem solar cell with a tunnel recombination junction based on ITO, NiO, and 2PACz. The novel junction improves the uniformity of the self-assembled monolayer and leads to narrower device efficiency distribution. The test showed that the cell reached an efficiency of 23.7%, an open-circuit voltage of 1.705 V, a short-circuit current density of 18.0 mA/cm2, and a fill factor of 77.2%. The researchers believe this new technology will be highly beneficial when scaling up to larger cell sizes.
