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...
这些系统性的改进抑制了电荷载流子复合，使得基于PM6(cas:1802013-83-7)，Y6(cas:2304444-49-1)的器件PCE高达17.2%，对照器件效率仅为14.5%。而在基于PM6:L8-BO器件中，当活性层厚度为90 nm时，最终获得了高达18.5%的PCE（第三方组织认证结果：18.32%），以及80.2%的高填充因子（FF）。更重要的是，当...
苏州大学袁建宇等人报道了挥发性固体添加剂在高效PM6:Y6系列非富勒烯太阳能电池中的作用。 作者报道了一种新型挥发性固体添加剂(VSA),2-羟基-4-甲氧基二苯甲酮(2-HM),其可实现高效的ONSC。而2-HM作为常见的PM6:Y6系列非富勒烯共混物的通用形态导向剂,即PM6:Y6、PM6:BTP-eC9、PM6:L8-BO,其在二元O...
SOLAR cellsFULLERENESPOLYMERSTwo 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 (P...
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 ...
