Energy Efficient Dissociation of Excitons to Free Charges
Maxim Tabachnyk, Samuel L. Smith, Leah R. Weiss +4
In photovoltaics (PVs) and artificial photosynthetic systems based on excitons, the question of how energy must be lost in overcoming the Coulomb barrier, converting excitons to fr…

Ultrafast Triplet Pair Formation and Subsequent Thermally Activated Dissociation Control Efficient Endothermic Singlet Exciton Fission
Hannah L. Stern, Alexandre Cheminal, Shane R. Yost +12
Singlet exciton fission (SF), the conversion of one spin-singlet exciton (S1) into two spin-triplet excitons (T1), could provide a means to overcome the Shockley-Queisser limit in…

A Silicon-Singlet Fission Parallel Tandem Solar Cell Exceeding 100 % External Quantum Efficiency
Luis M. Pazos, Ju Min Lee, Anton Kirch +3
Silicon solar cells dominate the solar cell market with record lab efficiencies reaching almost 26%. However, after 60 years of research, this efficiency saturated close to the the…
