An international research group has found that the presence of a few lattice defects in a kesterite PV cell material can actually improve efficiency, rather than lowering it. The group believes that kesterite PV cells could see mass production within the next decade.Researchers led by Iran's Tarbiat Modares University, the University of Tehran, the Shahid Bahonar University of Kerman, and Kuwait University applied defect analysis to 10.33% efficient kesterite solar cells, their analysis finds that through the carefully controlled addition of defects to the material, this efficiency could be increased ...Den vollständigen Artikel lesen ...
