Perovskite-HJT tandem solar cell based on phosphonic acid, self-assembled monolayer achieves 30.22% efficiency
Researchers in Switzerland have fabricated a perovskite-silicon tandem solar cells that utilizes a heterojunction cell as bottom device. The cell is said to circumvent the film formation issue associated with the use of phosphonic acid and achieve high efficiency levels.
