- Improved light-harvesting efficiency, reduced hysteresis, and superior performance with poly(3-hexyl-thiophene) were observed, marking it as the highest-performing PSC using this material with a PCE of 14.67%.
Article Abstract
A new perovskite solar cell (PSC) structure with a functionalized interface between perovskite and a hole transport material has been proposed in this report. The short circuit current density of PSC was notably enhanced with the novel architecture (with an increase of 8.7%), and a power conversion efficiency (PCE) of 16.93% was achieved. With the increased perovskite/hole conductor interface, hysteresis suppression was observed. The advantages of this structure in light-harvesting efficiency, trap density, and carrier separation rate were proved by various characterization and analysis studies. It is noteworthy that a PCE of 14.67% was achieved with poly(3-hexyl-thiophene), which to our knowledge is the highest performing PSC based on this material.
