Abstract：

The　high　photovoltaic　conversion　efficiency　(PCE)　of　ternary　organic　solar　cells　(OSCs)　based　on　PTB7-Th,　PC71BM　and　IEICO-4F　material　is　obtained,　the　short-circuit　current　density　(J　SC),　fill　factor　(FF),　and　open-circuit　voltage　is　25.90　mA　cm−2,　73.20%　and　0.71　V,　respectively.　PCE　is　as　high　as　13.53%.　It　is　the　highest　PCE　of　ternary　OSCs　based　on　PTB7-Th,　PC71BM　and　IEICO-4F　materials　for　all　we　know.　The　narrow　bandgap　material　of　IEICO-4F　is　deposited　on　PTB7-Th:PC71BM　bulk　heterojunction　(BHJ)　by　layer-by-layer　process.　We　constructed　the　dual　bandgap　active　layer　both　BHJ　and　pseudo-planar　heterojunction　(P-PHJ),　it　could　be　defined　as　ternary　BHJ/P-PHJ　of　OSCs.　This　type　of　OSCs　is　not　only　the　complementary　bandgap　material　of　the　active　layer,　but　also　increasing　the　donor/acceptor　(D/A)　interface.　The　excitons　generation　and　collection　of　the　device　are　increased　leading　a　higher　J　SC　and　FF.　The　semitransparent　OSCs　(ST-OSCs)　is　prepared　by　varying　the　thickness　of　Ag　electrode　and　PCE　can　reach　9.70%,　and　the　average　visible　light　transmittance　and　light　use　efficiency　of　ST-OSCs　are　improved　effectively.　©　2024　IOP　Publishing　Ltd.
