Ultrahydrophobic 3D/2D fluoroarene bilayer-based water-resistant perovskite solar cells with efficiencies exceeding 22.

TL;DR: This new approach provides water- and heat-resistant operationally stable PSCs with a record-level PCE, and enhances interfacial hole extraction, suppressing nonradiative carrier recombination and enabling a power conversion efficiency (PCE) >22%, the highest reported for 3D/2D architectures.
Journal ArticleDOI

Tailored Amphiphilic Molecular Mitigators for Stable Perovskite Solar Cells with 23.5% Efficiency

TL;DR: It is found that simple surface treatment with tBBAI significantly accelerates the charge extraction from the perovskite into the spiro-OMeTAD hole-transporter, while retarding the nonradiative charge carrier recombination, boosting the power conversion efficiency (PCE) of the PSC and reducing the hysteresis to barely detectable levels.
Journal ArticleDOI

Direct Contact of Selective Charge Extraction Layers Enables High-Efficiency Molecular Photovoltaics

TL;DR: In this paper, an advanced dye-sensitized solar cells (DSCs) architecture is presented, which achieves efficiencies of 13.1% under air mass 1.5 global, 100 mW cm −2 solar radiation, and power conversion efficiency of 32% under a standard Osram 930 Warm White fluorescent tube light at 1,000 lux intensity.
Journal ArticleDOI

Bifunctional Organic Spacers for Formamidinium-Based Hybrid Dion-Jacobson Two-Dimensional Perovskite Solar Cells.

TL;DR: This work demonstrates the first example of a formamidinium (FA) containing Dion-Jacobson 2D perovskite material characterized by the BFA n-1Pb nI3 n+1 formulation through employing a novel bifunctional organic spacer (B), namely 1,4-phenylenedimethanammonium (PDMA).
