Improving the efficiency of solar cells is the most effective route to reduce the levelised cost of electricity, and hence accelerating installations. Tandem structures offer a route to higher efficiencies (>35%) compared with single junction cells[1]. The tuneable bandgap and long charge-carrier lifetimes of metal halide perovskites make them ideal candidates for use as the top cell in tandem architectures, however their poor stability and large interfacial energetic losses complicate commercialisation[2].
Passivating these interfaces is effective in energetic loss mitigation although control over repeatability can be challenging. We have developed a novel passivation route that delivers increased control in passivation efficacy, observing strong enhancements to the perovskite radiative efficiency and photoluminescence lifetimes. Using our home-built stroboscopic scattering microscope (stroboSCAT), we show that the energy transfer dynamics are enhanced in the passivated samples, elucidating microscale insights into the passivation mechanism. Finally, we fabricated full photovoltaic devices that demonstrated successful interfacial passivation with increased repeatability compared with vapour passivation, highlighting the benefit of our approach.
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.
