合成了第一个中性Li@C60衍生物Li@PCBM。Li@PCBM在溶液中以单体-二聚体平衡存在，但在PCBM基质中以单体存在。完全分散的Li@PCBM n掺杂周围的空PCBM，与未掺杂的PCBM膜相比，费米能级提高了0.13 eV。杂化膜被用作PSC的ETL，提高了装置的效率。
Li@PCBM, the first neutral Li@C60 derivative, was synthesized. The Li@PCBM exists in a monomer-dimer equilibrium in solution but as a monomer in the PCBM matrix. The fully dispersed Li@PCBM n-doped the surrounding empty PCBM, raising the Fermi level by 0.13 eV compared with the undoped PCBM film. The hybrid films were utilized as an ETL for PSCs, promoting the efficiency of the device.
