Summary: The study found that using NC(70)BA as the third component material in inverted small molecule organic photovoltaic devices can achieve higher power conversion efficiency, attributed to the increased photocurrent density, open-circuit voltage, and fill factor. The hollow spherical structure of NC(70)BA helps improve the continuity of electron transport channels, and the optimization of molecular arrangement and crystallinity in the ternary photoactive layer also supports enhanced performance.

Summary: Suppressing charge recombination is crucial for enhancing the power conversion efficiency of organic solar cells (OSCs). The formation of both singlet and triplet charge transfer (CT) states in OSCs indicates that charge recombination via the triplet excited state is the main pathway for deactivation. However, it has been shown that charge separation from triplet excitons can occur in nonfullerene acceptor (NFA)-based OSCs, emphasizing the significance of minimizing the energy difference between singlet and triplet excited states of NFAs to suppress charge recombination.

Summary: The high trap density in organic solar cells is a major limitation for improving power conversion efficiencies. This study demonstrates that extending the donor core of nonfullerene acceptors from a heptacyclic unit to a nonacyclic unit efficiently reduces the trap density in the solar cells. This approach not only increases the mobility and inhibits charge-carrier recombination, but also achieves an impressive power conversion efficiency of 17.1% with a low nonradiative recombination energy loss.
