Perovskite-silicon tandem solar cell based on hybrid interconnecting layers achieves 28.47% efficiency

An international research team has designed a two-terminal perovskite-silicon tandem solar cell that utilizes new hybrid interconnecting layers to reduce recombination losses in the top perovskite device. The tandem cell achieved an impressive fill factor of 81. 8%, which the scientists said is the highest value ever reported for this cell technology to date. A group of researchers led by the Jinan University in China has developed a two-terminal (2T) perovskite-silicon tandem solar cell based on special hybrid interconnecting layers (ICLs) that prevent direct contact between the perovskite absorber ...
