Defect Passivation and Lithium Ion Coordination Via Hole Transporting Layer Modification for High Performance Inorganic Perovskite Solar Cells

Advanced Materials, Год журнала: 2023, Номер 36(4)

Опубликована: Авг. 24, 2023

Abstract Metal halide inorganic perovskite solar cells (PSCs) have great potential to achieve high efficiency with excellent thermal stability. However, the surface defect traps restrain achievement of open circuit voltage ( V OC ) and power conversion (PCE) devices due severe nonradiative charge recombination. Moreover, state‐of‐the‐art hole transporting layer (HTL) significantly hampers device moisture stability, even though it renders highest cell efficiency. Herein, a one‐stone‐two‐birds strategy is proposed using biocompatible material tryptamine (TA) as an additive in HTL. First, TA bearing electron rich moieties can favorably passivate defects films, reducing trap density prolonging lifetime. It results drastic improvement from 1.192 1.251 V, loss 0.48 V. The corresponding PSCs 21.8% PCE under 100 mW cm −2 illumination. Second, HTL coordinate lithium cations, retarding their reaction increasing stability Consequently, black phase films well preserved, maintain 90% initial after 800 h storage at relative humidity 25–35%, much higher than control devices.
