Perovskite/silicon solar module reaches 23.9% conversion efficiency
Belgian research centre imec, as part of its involvement in the Solliance and EnergyVille programmes, has announced that it has boosted the performance of its its 4 cm2 perovskite/silicon tandem photovoltaic module to a power conversion efficiency of 23.9%. imec says this is the first time that a module-on-cell stack structure has outperformed a standalone silicon solar cell.
perovskite cell (0.13 cm 2) on top of an IBC c-Si cell (4 cm 2). In this configuration, the power conversion efficiency of the small semi-transparent perovskite cell is 16.7%, outperforming the larger 4cm2 perovskite module due to better perovskite layer properties. Although less attractive from an industrial point of view, the overall power conversion efficiency of this cell-on-cell stack is as high as 25.3%.”
