Researchers employed blade coating instead of spin coating because the latter has scalability challenges.
Saudi and German researchers have developed a new solar cell with an impressive 31.2% efficiency. The cell, consisting of a perovskite-silicon tandem composite, could provide the foundation for higher-efficiency solar cells than currently exist.
The cell was developed by a collaboration between the King Abdullah University of Science and Technology (KAUST) and Helmholtz-Zentrum Berlin (HZB). According to the researchers behind the cell, it achieves efficient charge extraction and interface passivation.
The team enhanced the performance of blade-coated tandems by incorporating 2D perovskite layers at the bottom interface. These modifications reportedly increased the blade-coated tandem performance to a certified PCE of 31.2%.
