Perovskite solar cells (PSCs) are one of the most efficient and cost-effective PV technologies with efficiencies reaching the 26 % mark. They have attracted substantial interest due to their light-harvesting capacity combined with low-cost manufacturing. However, unsolved questions of perovskite stability are still a concern, challenging their potential of widespread commercialization. Factors able to induce degradation to metal halide perovskite (MOHP) materials and devices, such as humidity, atmosphere, bias voltage, temperature, or light exposure, have been the centre of multiple studies and debates for many years. The ISOS stability assessment protocols, elaborated after a consensus among leading international laboratories, have been recently upgraded to incorporate stressors involving the peculiarities of PSCs. However, the understanding of the different degradation mechanisms taking place in materials and solar cells will only be effective if the applied stressors are as closed as possible to an actual functioning solar cell under real (outdoor) conditions. The application of real outdoor conditions (ISOS-O protocol) implies that multiple stressors are imposed to the sample with large variability and with different dosages. In this talk, I will show our most recent publications related to the issues observed for the analysis of PSCs under outdoor stability analysis (e.g. encapsulation). I will also show our most recent results on the interface and bulk modification of PSCs with the aim of enhancing device stability (indoor and outdoor), in this case our work is focus on the use of organic additives and MXenes. Finally, I will briefly describe our current work on in-situ and operando characterization, under single or multiple stressors with time, on PSCs to elucidate degradation mechanisms in these devices.
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.
