In a recent study, COi8DFIC or O6T-4F was selected in a Tandem cell by computer assited design and gave a record PCE of 17.3∃% for fabricated organic solar cells.PMID 30093603
COi8DFIC or O6T-4F is frequently selected to blend with a narrow-bandgap donor material and another narrow bandgap acceptor material to fabricate ternary organic solar cells. The PTB7-Th:COi8DFIC:PC71BM ternary cells offered a PCE of 14.08%. By further adopting a post-annealing process, an outstanding PCE of 14.62% can be achieved. Furthermore, the device utilizing COi8DFIC exhibited a good thermal stability with PCEs over 13.5% in a wide temperature range (70–160 °C).

应用领域

COi 8DFIC是一种高效的非富勒烯受体材料，具有很强的近红外吸收，可作为n型小分子受体材料用于聚合物太阳能电池的制备。

COi 8DFIC主要用作OPV器件中的非富勒烯受体。它具有宽的吸收光谱，使其能够吸收包括可见光和近红外区域在内的宽范围波长的光。该特性允许有效利用更宽范围的太阳辐射，提高了OPV器件的光捕获能力。COi 8DFIC可用作OFET器件的电子传输材料。
