Abstract:	摘要： A planar heterojunction organic solar cell (OSC) with high internal quantum efficiency (IQE=95.6% at 590nm) was demonstrated based on boron subphthalocyanine chloride (SubPc) and C60 as the electron donor and acceptor materials. A thin layer of N,N-dicarbazolyl-3,5-benzene (mCP), acting as an electron and exciton blocking layer, was inserted between the ITO anode and the SubPc layer to prevent leakage current and exciton quenching. In the optimized device, a mCP thickness of 3nm was thick enough to block the excitons (as suggested by a high IQE and longer-lived photoluminescence), resulting in an open circuit voltage of 1.09V, a short circuit current of 7.87mA/cm2, a fill factor of 59, and a power conversion efficiency of 5.08%. Increasing the mCP thickness resulted in increased serial resistance and SubPc crystallization that reduced the fill factor, VOC, and JSC. Due to the narrow absorption band of SubPC (71nm at the full-width-at-half-maximum), this high performance (both in peak IQE and VOC) device has the potential to be used as a subcell in a spectral splitting solar cell module. •High IQE SubPc/C60 OPV device was fabricated by inserting mCP between ITO and SubPc.•Exciton and electron blocking resulted in the high IQE.•The device showed high efficiency of 5.08%, with VOC of 1.09V and IQE of 95.6%. 出版者： Amsterdam: Elsevier B.V 出版日期： 2014-03-01 出處： Solar energy materials and solar cells, 2014-03, Vol.122, p.264-270 資源來源： ScienceDirect (Elsevier) Journals 版權： 2013 Elsevier B.V. 版權： 2015 INIST-CNRS 識別號： ISSN: 0927-0248 識別號： EISSN: 1879-3398 識別號： DOI: 10.1016/j.solmat.2013.12.006
