摘要: Highly efficient organic tandem solar cell with peak power conversion efficiency (PCE) of 7.66% has been demonstrated by simply stacking two same boron subphthalocyanine (SubPc):C-70 bulk heterojunction devices, a high active inter-connecting layer composed bathophenanthroline (Bphen)/Silver/hexadecafluoro-copper-phthalocyanine (F16CuPc)/MoO3. We find that F16CuPc plays an important role which extends the recombination zone, facilitates extraction hole and carrier recombination. The measured PCE corresponds to 38% increase compared optimal single cell. (C) 2014 Elsevier B.V. All rights reserved.
