The wide variations in bandgaps offered by metal halide perovskites provide a unique opportunity to develop multijunction thin-film solar cells with an efficiency that surpass the limits of a single-absorber photovoltaic devices. Additionally, perovskite-based multijunction solar cells enable lower the levelized cost of energy. Recent results on perovskite-perovskite and perovskite-copper indium gallium selenide (CIGS) multijunction cells will be presented. Often wide-bandgap mixed-halide perovskites and narrow-bandgap mixed-metal perovskites suffer from non-radiative recombination due to bulk traps and interfacial recombination centers that limit the open-circuit voltage in wide-bandgap sub-cells and restrict photocurrent for narrow-bandgap materials. We studied the origin of these traps with photocurrent spectroscopy and absolute photoluminescence spectroscopy and employ passivation strategies to eliminate losses and increase stability. Combined with reducing parasitic absorption losses using optical simulations as guide, this allows fabricating efficient multi-junction cells in all-perovskite configurations and in combination with other thin-film semiconductors such as CIGS. Collectively, these strategies enable monolithic tandem solar cells with a power-conversion efficiency of 26%.
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.
