Mechanically stacked 4-terminal III-V/Si tandem solar cells
Essig, S.; Allebe, C.; Geisz, J. F.; Steiner, M. A.; Barraud, L.; Descoeudres, A.; et al. (2017)We developed 4-terminal III-V/Si dual-junction solar cells that reach certified record 1-sun efficiencies over 32%. These efficiency values exceed the theoretical efficiency limit of single-junction solar cells and prove ... -
Raising the one-sun conversion efficiency of III-V/Si solar cells to 32.8% for two junctions and 35.9% for three junctions
Essig, S.; Allebe, C.; Remo, T.; Geisz, J. F.; Steiner, M. A.; Horowitz, K.; et al. (2017)Today''s dominant photovoltaic technologies rely on single-junction devices, which are approaching their practical efficiency limit of 25-27%. Therefore, researchers are increasingly turning to multi-junction devices, which ...
