Scientists from the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have fabricated a tandem solar cell based on a perovskite top cell and a heterojunction (HJT) bottom device ...

Will Norman asks if mass-scale deployment of perovskite technology is now imminent and whether it could unseat crystalline ...

Researchers have achieved an efficiency of 24.6% with a copper indium gallium selenide (CIGS) and perovskite tandem solar cell.

The 9 cm² cell consists of a top cell based on a perovskite absorber and a bottom cell with a heterojunction (HJT) structure. The results improve on the 29.8% efficiency CEA and 3Sun achieved for ...
