Suzhou Maxwell has secured a certified power conversion efficiency of 32.38% for a perovskite/silicon heterojunction (SHJ) tandem solar cell.

UNSW researchers boosted TOPCon solar cell efficiency by locally thinning the rear poly-Si layer, reducing parasitic absorption while preserving wafer integrity. The champion cell built with this ...

Researchers at École Polytechnique Fédérale de Lausanne (EPFL) and Center Suisse d’Electronique et de Microtechnique (CSEM) in Switzerland developed a novel single-step thermal annealing process for ...
