Researchers in China have developed a dipolar passivation method that reduces defects and improves charge transport in solar cells based on narrow-bandgap tin lead perovskite. The approach has enabled the fabrication of all-perovskite tandem solar cells with efficiencies of around 30% and enhanced stability,A group of researchers led by Nanjing University in China has developed a perovskite solar cell based on a dipolar passivation strategy that reportedly reduces defect density at the buried interface of mixed narrow-bandgap tin lead (Sn-Pb) perovskites, while enabling precise energy-level alignment ...Den vollständigen Artikel lesen ...
