LT-S8031 PAPzO >98%
PAPzO and PAPz, which exhibit synergistic interactions with SnO2 and perovskites. These molecules decrease charge trap densities, elongate carrier lifetimes, and retard perovskite crystallization. PAPzO, with a stronger binding energy and better aligned energy levels, enables a power conversion efficiency (PCE) of 26.04% and long-term stability, maintaining 91.24% of its original PCE after 1,200 h of continuous maximum power point tracking.

LT-S8040 4PABCz >98%
The 4PABCz molecules exhibited strong intermolecular p–p interactions and an out-of-plane dipole, enabling the formation of tightly assembled and face-on oriented HTLs to achieve dense coverage and facilitated hole extraction on substrates.
Moreover, the unique configuration of the 4PABCz-covered substrates effectively regulated the crystallization of perovskite films and released residual stress. As a result, the inverted PSCs on FTO substrates achieved a champion power conversion efficiency (PCE) of 26.90% (certified 26.81% for reverse-scan and 25.96% for steadystate), retaining 93.98% of their initial efficiency after 1000 h of maximum power point tracking under the ISOS-L-2 protocol.
