Abstract
Halide perovskites are a class of hybrid organic–inorganic semiconductors that have rapidly transformed photovoltaics R&D over the past 15 years, thanks to their outstanding optoelectronic properties and low-cost fabrication potential. Their rise has led to remarkable improvements in solar cell efficiencies, positioning them as strong candidates for next-generation photovoltaic technologies.
In this seminar, I will briefly review the key factors behind this success and then focus on the main challenges still hindering large-scale commercialization. In particular, I will discuss stability issues and their impact on long-term device performance, as well as the problem of lead toxicity in high-efficiency perovskite compositions, examining current strategies for lead replacement and the associated trade-offs. These aspects will be addressed through recent research efforts, highlighting ongoing work aimed at improving device stability and developing more sustainable materials.
