全聚合(he)物(wu)太阳(yang)能电池（APSC）具(ju)有优异的(de)光(guang)/热(re)稳(wen)定性及柔韧拉伸性能，被认为是柔性电源(yuan)系(xi)统中最有潜力(li)的应(ying)用之一。得益于非富勒烯受(shou)体(ti)(ti)材料的快速发展，高性(xing)能(neng)聚(ju)(ju)小分子(zi)受(shou)体(ti)(ti)被不断开发。相(xiang)比而(er)言(yan)，高性(xing)能(neng)聚(ju)(ju)合(he)物(wu)给(ji)体(ti)(ti)的发展相(xiang)对滞后。如何(he)设(she)计合(he)成新型聚(ju)(ju)合(he)物(wu)给(ji)体(ti)(ti)材料，并调控(kong)给(ji)/受(shou)体分子间堆(dui)积和取(qu)向，阐(chan)明给(ji)/受体分子间相(xiang)互作(zuo)用与光伏性能(neng)之(zhi)间的关系，将有(you)力助推高(gao)效(xiao)全(quan)聚有(you)机太阳能(neng)电池的发展。
近日，中国科学(xue)院(yuan)青岛生物能源与(yu)过(guo)程研(yan)(yan)究所研(yan)(yan)究员包西昌带领的先(xian)进有机功能材料与(yu)器件(jian)研(yan)(yan)究组在(zai)该领域取得重要进展。研究通(tong)过降低给体材料主骨架之间的电荷转(zhuan)移态和醌类共振效应，设(she)计合(he)成全(quan)新(xin)的超宽(kuan)带隙（Eopt = 2.24 eV）聚合物给体材料(liao)（图1）。该(gai)材料(liao)具(ju)有较高消光系数且吸收(shou)光谱(pu)完美覆盖最强太阳辐射范围，并与受体材料(liao)具(ju)有良好的混溶性和较强的分子间相互作(zuo)用。该(gai)工(gong)作(zuo)获得了效率(lv)为(wei)15.3%和17.1%的两组分和(he)三(san)组分APSC（与(yu)当下经典给(ji)体(ti)材料相(xiang)(xiang)媲(pi)美）。该研究为全聚有机太阳能电池给(ji)体(ti)材料的(de)发展提供(gong)了(le)新颖(ying)的(de)设计(ji)理(li)念和(he)材料结构。相(xiang)(xiang)关成果发表在《先进功能材料》（Advanced Functional Materials）上。
此外(wai)，共轭聚合(he)物之间的(de)(de)强链间缠结易形成(cheng)较差的(de)(de)相(xiang)分离、低混(hun)合(he)熵(shang)，难以调(diao)控活性(xing)层的(de)(de)结晶和形貌(mao)，进(jin)而(er)限(xian)制(zhi)光伏性(xing)能(neng)的(de)(de)提升(sheng)。对此，科研人员开发的(de)(de)具有良好混(hun)溶(rong)性(xing)的(de)(de)聚合(he)物给体，可以有效渗透到给/受(shou)体（D/A）聚(ju)集域中，优化了(le)全(quan)聚(ju)合物活(huo)性(xing)层(ceng)内的(de)分子堆积(ji)和相分离，实(shi)现了(le)激子和载流(liu)子的(de)高效利用（图2）。具有(you)体异(yi)质(zhi)结（BHJ）结构(gou)的(de)三元APSC实现(xian)了17.64%的效(xiao)率和高的厚膜耐受性。第三(san)组分渗透可有效(xiao)地促进更多混合相的形成，并独立地优(you)化D/A有序(xu)堆积，在(zai)构建(jian)理想伪平(ping)面异质(zhi)结(jie)（PPHJ）活(huo)性层方面显示出独特的优势(shi)。具有PPHJ结构的三元APSC获(huo)得了17.94%的(de)效率并表现出优异(yi)的(de)器件稳定性(xing)。利(li)用良好(hao)混溶性(xing)第三组分(fen)独立(li)诱(you)导D/A有序堆积，在(zai)构(gou)建高性能APSC方(fang)面颇具潜力。相关成果发表在《能源与环境科学》（Energy & Environmental Science）上。
