Bifacial　dye-sensitized　solar　cells　(DSSCs)　are　regarded　as　promising　solar　energy　conversion　devices　with　high　efficiency　and　less　resource　consumption.　In　this　work,　a　highly　transparent　and　efficient　counter　electrode　(CE)　is　fabricated　by　introducing　highly　dispersed　single　Pt　atoms　doped　into　the　van　der　Waals　layer-by-layer　epitaxially　grown　Zn-TCPP　thin　film　(Zn-TCPP-Pt).　The　resulting　Zn-TCPP-Pt　CE　has　similar　catalytic　activity　to　commercial　Pt　CE　but　shows　a　better　light　transmission　capacity　in　the　range　of　visible　light.　The　bifacial　DSSC　with　Zn-TCPP-Pt　thin　film　CE　achieves　high　power　conversion　efficiencies　of　5.48　and　4.88%　under　front-side　and　rear-side　irradiation,　respectively.　With　maximized　atomic　efficiency,　excellent　performance　was　obtained　with　about　1%　Pt　content　and　highly　transparent　CEs.　Therefore,　the　light　energy　resource　utilization　rate　of　such　less　Pt　and　transparence　CE　is　greatly　improved　in　bifacial　dye-sensitized　solar　cells,　making　it　a　promising　candidate　to　replace　Pt　CE.　Copyright　©　2019　American　Chemical　Society.
