1T-Rich 2D-WS2 as an interfacial agent to escalate photo-induced charge transfer dynamics in dopant-free perovskite solar cells

The deficiency in the photo-induced charge transfer dynamics at the perovskite-charge transport layer interfaces due to depleted energy alignment and surface traps impedes perovskite solar cells performance improvement. Herein, we suggest a simplistic interfacial engineering protocol to overcome current challenges.
