SERIS builds 22.1%-efficient perovskite-silicon tandem solar cell based on double-sided polysilicon layers

SERIS researchers developed a 16-cm² perovskite-silicon tandem solar cell with a double-sided TOPCon bottom cell, enhancing passivation, reducing recombination, and increasing voltage and fill factor.Researchers from the Solar Energy Research Institute of Singapore (SERIS) in Singapore have fabricated a perovskite-silicon tandem solar cell based on a bottom TOPCon device relying on double-sided (DS) thin polysilicon (poly-Si) layers. In standard single-sided TOPCon (SS-TOPCon) solar cells, charge-carrier selectivity is achieved using a heavily boron-doped front surface layer and a rear stack made ...
