Herein, the fabrication of a four‐terminal tandem incorporating a front transparent cell made using a 7 nm Ag back electrode and a PM6:L8‐BO blend which exhibits a bandgap close to the optimal according to the detailed balance theory is reported. For the opaque back...
By utilizing two widely used high-boiling, non-halogenated green solvents鈥攐-xylene (o-XY) and toluene (Tol) 鈥攊n the fabrication of PM6: L8-BO, we achieve power conversion efficiencies (PCEs) of 18.20% and 17.36%, respectively. Additionally, a module fabricated with o-XY demonstrates ...
Two kinds of polymer solar cells (PSCs) were fabricated with polymer donor PM6 and small molecule non‐fullerene acceptor L8‐BO as accepted based on bulk heterojunction (BHJ) or layer‐by‐layer (LbL) structure. The power conversion efficiency (PCE) of 18.43 % and 17.8...
