Lead sulfide colloidal quantum dots (PbS CQD) have took a firm position as part of the optoelectronic applications, such as next generation photovoltaics.1 They offer multiple valuable properties like high stability and infrared absorption or low cost and solution processability. Though, in particular the broad optical absorption, size-tunable bandgaps (0.5 – 2.0 eV) and multiple exciton generation, makes them attractive candidates for effective and durable solar cells. Over the past years, a great improvement in the photovoltaic performance of PbS CQD devices was observed. Better CQD solar cells have been made possible by an increased understanding of the material properties like effects of surface passivation2, band engineering or charge dynamics3 in CQD films.4 In this study we will investigate the carrier dynamics in PbS CQD devices utilizing mixed halide passivation of PbS quantum dot of two different sizes (1.3 eV and 1.07 eV). Main focus will be put on temperature controlled transient photocurrent and photovoltage decay measurements in devices of following structure: Indium doped tin oxide (ITO)/Aluminum doped zinc oxide (AZO)/Mixed-halide passivated PbS CQD/1,2-ethanedithiol passivated PbS CQD/Gold. Combined with other substantial measurements it will provide an insight to better understanding of the charge transport and recombination under broad temperature range from 15-130°C, together with possible defects and trap state formation in these devices and expectantly allow for future improvement in device engineering.
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.
