High-Performance Organic Solar Cells from Non-Halogenated Solvents

Di Wang et al.

Summary: The study demonstrates that high-performance organic solar cells (OSCs) can be obtained from hot spin processing of different non-halogenated solvents, achieving the highest reported efficiency of OSCs so far. The phase evolution of ternary blends during solution-to-solid transition is found to be correlated to the substrate temperature, and optimal blend films can be secured in various non-halogenated solvents with elevated substrate temperature. As a result, high-performance OSCs with excellent power conversion efficiencies have been achieved in o-xylene, p-xylene, and toluene, respectively, representing the best-performing OSCs made from non-halogenated solvents to date.

A New End Group on Nonfullerene Acceptors Endows Efficient Organic Solar Cells with Low Energy Losses

Youwen Pan et al.

Summary: Chemical modifications were made to the famous Y-series nonfullerene acceptor BTP-4Cl-BO, resulting in the synthesis of two novel NFAs, BTP-T-2Cl and BTP-T-3Cl, with extended pi-conjugation through the fusing of IC group with a chlorinated thiophene ring. The OSC using BTP-T-2Cl exhibited a modest PCE of 14.89% with an extraordinary low energy loss of 0.49 eV, while the OSC using BTP-T-3Cl showed a higher PCE of 17.61% but with a slightly bigger energy loss of 0.51 eV. Adopting two NFAs of BTP-T-3Cl and BTP-4Cl-BO, a ternary OSC achieved an impressive PCE of 18.21%, demonstrating the effectiveness of expanding end groups of NFAs with electron-donating rings in reducing energy losses for OSCs.
