Emerging semiconductors, particularly organic conjugated molecules and metal halide perovskites, are transforming the semiconductor industry and serving as foundational materials for next-generation technologies, including solar panels, displays, lighting, and sensing devices. In photovoltaics, perovskite solar cells have already achieved an impressive power conversion efficiency of 27%, while organic solar cells have surpassed 20%. However, despite their remarkable device performance, several challenges still hinder large-scale commercialisation.
A key factor in realising the full commercial potential of organic solar cells is stability; a photovoltaic device must possess a sufficiently long lifespan to exceed the operational requirements of its intended application. The limited stability of conventional fullerene-based organic solar cells has long been recognised as a major challenge, with multiple degradation mechanisms leading to rapid performance losses under illumination, ambient exposure, and thermal stress. Nevertheless, the transition from fullerene to non-fullerene acceptors, alongside significant advances in molecular and device design, has opened exciting opportunities to fully address this issue.
For perovskite solar cells, one of the most critical concerns is their potentially high ecotoxicity, primarily due to the use and subsequent leaching of excessive amounts of lead into the environment over the product’s lifetime. How to minimise the risks of lead release fromthese materials into the environment without compromising device performance remains a majorchallenge.
In this talk, I will summarize my group's recent research progress in addressing the stability and environmental challenges of organic and perovskite materials and solar cells. For organic solar cells, I will highlight the distinct roles of donor and acceptor materials in degradation and propose potential strategies to mitigate these degradation mechanisms. For perovskite solar cells, I will examine the lead leaching mechanisms of halide perovskite materials under various environmental conditions and demonstrate how rational materials and device design can help overcome this challenge.
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.
