From: Constructing molecular bridge for high-efficiency and stable perovskite solar cells based on P3HT
Charge density differences of a PVK/MDN, b PVK-VI/MDN, c PVK/RDN, and d PVK-VI/RDN. PVK-VI denotes the perovskite with I vacancy, and ΔE expresses the binding energy. Local perovskite is displayed for clarity. The yellow and cyan regions represent electron accumulation and depletion, respectively. Independent gradient model based on Hirshfeld partition (IGMH) of MDN/P3HT dimer complexes with different geometries e and f.
