Electrostatic Potential Complementarity for Thickness‐Tolerant Cathode Interlayers in High‐Efficiency Organic and Tandem Solar Cells

open access: yesAdvanced Science, EarlyView.
Two model molecules — trimesic acid (TMA) and phloroglucinol (PG) — with opposite central electrostatic potential (ESP) distributions are employed to elucidate how molecular electrostatic interactions regulate the cathode interlayer (CIL) PDINN. Electrostatic potential complementarity is revealed as the intrinsic origin of thickness sensitivity in CILs,

Degradation Mechanisms Associated with Electron‐Blocking Layers in Inverted Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
The effects of the three typical EBLs NiOx, PTAA, and 2PACz on the photovoltaic performance and degradation mechanisms are investigated under light soaking and solar‐thermal cycling conditions of corresponding PSCs, demonstrating that 2PACz is the best EBL due to the better interface contact and lower lattice distortion.
