In this talk I will present an overview of our activities at ICFO on the development of hybrid 2D-CQD photodetectors. I will start by the first demonstration of a highly sensitive graphene-PbS CQD photodetector, the advances made in increasing external quantum efficiency transforming PbS QDs from a passive sensitizer to an active CQD Photodiode and then showcase some use case examples in its operation in image sensors and wearable applications. Then I will discuss briefly the implications of replacing graphene with semiconducting TMD 2D materials and an overview of our activities in this class of hybrid detectors. In the second part of the talk I will discuss recent progress on efficient SWIR QD LEDs and their use in conjunction with a CQD photodiode to demonstrate an optical transmission link at the eye-safe 1550 nm based entirely on CQD optoelectronics (LEDs and photodetectors). In the last part of my talk, I will discuss recent efforts in extending the spectral coverage of PbS QD photodetectors towards the mid and long wave infrared exploiting intersubband transitions in heavily doped QD films.
nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
