Polar side-chain tuning of perylene diimide and fluorene-based cathode interfacial material for high-performance inverted perovskite solar cells

Abstract

Cathode interface layer (CIL) plays an important role in the inverted perovskite solar cell (PVSC) to correct the mismatched energy level, improve electron extraction, and passivate interfacial defects. Herein, we...

Perylene-diimide for organic solar cells: current scenario and prospects in molecular geometric, functionalization, and optoelectronic properties

“…323 This technology harnesses unlimited solar energy to efficiently oxidize and remove diverse organic pollutants. [324][325][326][327][328][329][330][331][332] Recently, solution-processed PDI derivatives functionalized with electron-donating groups (e.g., cyno or carboxylic groups) are integrated as an additive for passivating under-coordinated Pb 2+ cations in PbI 6 octahedral in perovskite lms. 333 In this case, the PDl-based OSMs play a dual-functional role, passivating surface trap states of the perovskite lattices by forming a Lewis acid-base adduct with the under-coordinated frameworks while contributing efficient charge extraction and transfer characteristics along PDI layer towards electrode of devices.…”

Recent advances in electrode interface modifications in perovskite solar cells

“…[66][67][68][69][70] To replace BCP, multiple EIMs such as organic small molecules, polymers, organic-inorganic hybrid compounds, and inorganic metal oxides have been developed and shown enhancement in both the efficiency and the stability for PSCs. [71][72][73][74][75][76][77] Organicinorganic hybrid EIMs with the advantages of both the structure tunability of organic molecules and the stability of inorganic materials have the potential to overcome the instability of the cathode interface.
