Russian doping cases: Wada investigation finds more than 300 cases from Moscow laboratory

Wada revealed details of a state-sponsored doping programme in 2015, and declared the Russian Anti-Doping Agency (Rusada) non-compliant with the World Anti-Doping Code. But Wada’s executive committee voted to reinstate Rusada in September 2018, subject to a number of strict conditions. The move was condemned in some circles at the time with one critic calling it…

Continuously graded-doped SnO2 for efficient n–i–p perovskite solar cells

Conventional n–i–p architecture remains a robust platform for scalable perovskite photovoltaics1,2, yet its steady-state efficiency has stagnated at ~26% (ref.3), lagging behind p–i–n counterparts4. This performance gap arises from persistent non-radiative recombination at textured electron transport layer (ETL)/perovskite interfaces, yet the underlying physical origin remains unclear. Here, we uncover that these losses originate from the…
