"Two-step Thermal Annealing: An Effective Route for 15% Efficient Quasi-2D Perovskite Solar Cells"

Low‐dimensional perovskites (LDP) are nowadays recognized as promising materials for the realization of highly performing photovoltaic cells. However, issues related to film morphology, composition, crystal quality and material homogeneity limit the device performances and reproducibility. In this work, we implement a robust method for the deposition of a LDP mixing methylammonium (MA) and phenylethylammonium (PEA) cations to create the mixed system (PEA)2MA39Pb40I121 by using a two‐step thermal annealing treatment (at 60 and 100 °C). Our approach results in LDP films with high crystal quality and enhanced carrier lifetime, which double the power conversion efficiency of reference devices, reaching up to 15%.

"Lead or No Lead? Availability, Toxicity, Sustainability and Environmental Impact of Lead-Free Perovskites Solar Cells"

In this perspective we analysed LCA and other data for the most suitable elements proposed as substituents for lead in perovskite solar cells (PSCs), since lead is a well-known neurotoxic and persistent pollutant. However, all other elements present one to three orders of magnitude higher environmental impact than lead, are too scarce, or - except for Ge and Ag - are also dangerous for human health to various degrees. Furthermore, lead can be easily recycled and can be safely encapsulated in solar panels, whereas every year by burning coal alone we emit 80'000 metric tons of lead into the atmosphere.

In summary, it is argued that the advantages of using lead in photovoltaic panels – when including proper encapsulation and recycling - outweigh the risks associated with its manufacturing.

2020 Journal of Materials Chemistry Lectureship winner: Giulia Grancini

Professor Giulia Grancini has been selected as the winner of the Journal of Materials Chemistry Lectureship 2020. To celebrate, we have put together a collection of her publications in Royal Society of Chemistry journals.

100 donne contro gli stereotipi (100 women against stereotypes)

(English below)

Nei mezzi di informazione moderni (TV, giornali) a spiegare i fenomeni sociali e politici sono quasi sempre gli uomini (82% dei casi). Eppure le esperte ci sono. Per ridurre questo gender gap l'Osservatorio di Pavia e l'associazione Gi.U.Li.A., con lo sviluppo di Fondazione Bracco e con il supporto della Rappresentanza in Italia della Commissione Europea, hanno lanciato, una banca dati online a disposizione degli operatori dell'informazione con oltre 130 nomi e CV di esperte in STEM (Science Technology Engineerings and Mathematics), fra cui la Prof.ssa Giulia Grancini, e oltre 70 in Economia e Finanza.

In today's media (TV, newspapers) the vast majority of experts are men (82%), even though there are many women experts. To reduce this gender gap Osservatorio di Pavia and Associazione Gi.U.Li.A., in collaboration with Fondazione Bracco and the support of the European Commission, launched, an online database for journalists to select over 130 names and CVs of femal experts in STEM (Science Technology Engineerings and Mathematics), among which features Prof. Giulia Grancini , and over 70 in Economy and Finance.
