A highly efficient acceptor material for organic solar cells (OSCs)--based on perylene diimide (PDI) dimers--shows significantly reduced aggregation compared to monomeric PDI. The dimeric PDI shows a best power conversion efficiency (PCE) approximately 300 times that of the monomeric PDI when blended with a conjugate polymer (BDTTTT-C-T) and with 1,8-diiodooctane as co-solvent (5%). This shows that non-fullerene materials also hold promise for efficient OSCs.
一种基于苝二酰亚胺(PDI)二聚体的高效有机太阳能电池(OSC)受体材料与单体 PDI 相比,聚集程度明显降低。当与共轭聚合物(BDTTTT-C-T)和 1,8-二碘辛烷作为共溶剂(5%)共混时,二聚体 PDI 的最佳功率转换效率(PCE)比单体 PDI 高出约 300 倍。这表明非富勒烯材料也有望用于高效 OSC。
