Abstract
This study developed a star-shaped 3,6-Bis(5-(4,4′-bis(3-azidopropyl)-[1,1 ′:3 ′,1 ′-terphenyl]-5 ′-yl)-thien-2-yl)-2,5-bis(2-ethylhexyl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione (DPPTPTA) additive in combination with electrospun carbon nano fibers integrated bimetallic copper-cobalt phosphide (DPPTPTA/CuCoP/CNF) as an interface layer for dye-sensitized solar cells (DSSCs). This interface layer is different from conventional blend films. As a multifunctional additive, DPPTPTA provides ladder-like energy levels for efficient charge separation, changing the morphology of the interface layer and improving performance. The CuCoP/CNF has high electrocatalytic activity and enhanced ionic conductivity. The interface layer ensures efficient charge transfer at the electrode/electrolyte interface with lower electron recombination rate in the DSSC, and it is expected that the photoelectric conversion efficiency (η) of the DSSC can be greatly improved under the condition of 1 sun (AM 1.5G, 100 mW cm-2), and the local boundary is constructed through the interface layer. It ensures long-term thermal stability; and it is expected to have higher η under indoor light condition test, which is one of the most promising devices for renewable energy generation.
