Impact of interlayer application on band bending for improved electron extraction for efficient flexible perovskite mini-modules

The development of highly efficient lightweight flexible perovskite solar cells (PSCs) opens the way to high-throughput roll-to-roll manufacturing processes and new applications such as building integration and mobile products. Flexible PSCs are generally ...

Tailored lead iodide growth for efficient flexible perovskite solar cells and thin-film tandem devices

Romain Carron, Fan Fu

Flexible perovskite solar cells (PSCs) hold great promise for the low-cost roll-to-roll production of lightweight single- and multijunction photovoltaic devices. Among the different deposition methods used for the perovskite absorber, the two-step hybrid v ...

Self-formation of hexagonal nanotemplates for growth of pyramidal quantum dots by metalorganic vapor phase epitaxy on patterned substrates

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Romain Carron, Pascal Gallo, Alessandro Surrente

We demonstrate the self-formation of hexagonal nanotemplates on GaAs (111)B substrates patterned with arrays of inverted tetrahedral pyramids during metal-organic vapor phase epitaxy and its role in producing high-symmetry, site-controlled quantum dots (QD ...

Dilute-Nitride Low-Dimensional Nanostructures Formed on Non-Planar Substrates

Romain Carron

The properties of semiconductors heterostructures of nanoscopic dimensions change from that of bulk material according to the rules of quantum mechanics. The planar quantum wells (QWs) are widely used in various diode and laser devices thanks to the relati ...

Magneto-optical properties of single site-controlled InGaAsN quantum wires grown on prepatterned GaAs substrates

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Romain Carron, Pascal Gallo, Marco Felici

The properties of single site-controlled InGaAsN quantum wires (QWRs)-both untreated and irradiated with atomic hydrogen-are probed by micro-magnetophotoluminescence spectroscopy. The strong anisotropy of the diamagnetic shift measured for different orient ...

Reduced temperature sensitivity of the polarization properties of hydrogenated InGaAsN V-groove quantum wires

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Romain Carron, Marco Felici

We investigated the effects of hydrogen irradiation on the degree of linear polarization, rho, of the light emitted by site-controlled, dilute-nitride InGaAsN V-groove quantum wires (QWRs). While in the as-grown sample the polarization of the QWR emission ...
