Purification of small bandgap fullerenes

open access: yes, 1997
A process for purification of the previously insoluble empty fullerenes and endohedral metallofullerenes was developed, based on sublimation from the soot and subsequent solubilization by electrochemical reduction.

Revisiting Open‐Circuit Voltage in Heterojunction‐Scarce Organic Solar Cells

open access: yesElectron, EarlyView.
This work establishes an analytic framework based on the interplay between the composition‐driven density of states and geminate recombination for understanding the open‐circuit voltage of bulk heterojunction‐reduced organic solar cells. ABSTRACT Organic solar cells (OSCs) have reached power conversion efficiencies (PCEs) above 21%, yet their market ...

Non‐fullerene acceptor aggregation regulation via additives dipole moment leads to 19.9% power conversion efficiency in bilayer organic solar cells

open access: yesFlexMat, EarlyView.
Additives interact with non‐fullerene acceptors to modulate their aggregation behavior and molecular orientation via optimizing crystallization kinetics. The optimized morphology effectively suppresses charge carrier recombination and enhances charge transport. Notably, 2‐chloro‐1,3‐dibromobenzene with the dipole moments of 2.56 D enables the PM6/L8‐BO
