Photocurrent and photoluminescence mapping of Au/FA0.9MA0.1PbI3 junctions: Probing carrier diffusion and thermo-optical degradation

Jiazhuo Nie, Zhelu Hu, Alexandre Zimmers, Zhuoying Chen, Lionel Aigouy

We present a combined photocurrent (PC) and photoluminescence (PL) imaging study of FA0.9MA0.1PbI3 perovskite thin films patterned with Au gold pads forming planar Schottky junctions. From these measurements, we extract a room temperature carrier diffusion length between 6 and 10 μm, consistent…

Surface Passivation of HgTe Nanocrystals Enabling EG/2 Open-Circuit Voltage and Their Coupling to Dielectric Cavity for Narrow Detection

Albin Colle, Clement Gureghian, Dario Mastrippolito, Mariarosa Cavallo, Jiho Roh, Marco Paye, Tommaso Gemo, Diogo Almeida, Adrien Khalili, Yoann Prado, Xavier Lafosse, Sandrine Ithurria, Mathieu G Silly, Pavel Dudin, James K Utterback, José Avila, Debora Pierucci, Emmanuel Lhuillier

Colloidal HgTe nanocrystals (NCs) offer a versatile, solution-processable platform for infrared optoelectronics, yet their integration into high-performance diodes has long been hindered by surface-trap-limited open-circuit voltage (V OC ), high dark currents, and insufficient thermal robustness.…

InAs Nanocrystal-based Infrared Imager Operating beyond Telecom Wavelengths

Youngsang Park, Hyeonjun Jeong, Adrien Khalili, Seongmin Park, Quentin Guer, Clement Gureghian, Tommaso Gemo, Jiho Roh, Albin Colle, Dario Mastrippolito, Mariarosa Cavallo, Jisoo Oh, Marco Paye, Maxime Lebreton, Francois Coursaget, James Utterback, Sandrine Ithurria, Nicolas Péré Laperne, Debora Pierucci, Victor Parahyba, David Darson, Sohee Jeong, Emmanuel Lhuillier

Colloidal III-V nanocrystals offer a promising route toward low-cost, CMOS-compatible infrared imaging beyond the silicon band gap. Here, we demonstrate a short-wave infrared (SWIR) imager operating at telecom wavelengths based on InAs nanocrystal photoconductors. InAs nanocrystals, with a spectral…

Beyond the Surface: Three-Dimensional Distribution and Defect Passivation of Self-Assembled Monolayers in Perovskite Solar Cells

Dongjiu Zhang, Smail Mostefaoui, Daming Zheng, José Alvarez, Rebeca Lopez-Adams, Jiazhuo Nie, Sergio Vlaic, Yusheng Wang, Baoquan Sun, Philippe Lang, Thierry Pauporté, Lionel Aigouy, Jérôme Aléon, Zhuoying Chen

Self-assembled monolayers (SAMs) are widely employed to tune interfacial properties in perovskite solar cells (PSCs), yet have so far been regarded as strictly two-dimensional surface modifiers. Here, we uncover the three-dimensional nature of perfluorinated silanolbased SAMs applied onto…
