An international research group has developed a solar cell based on a lead-free perovskite material known as Cs2AgBiBr6. The cell's absorber was doped with trans-polyacetylene, which reportedly helped the device improve its efficiency by over 20%. A group of researchers led by the University of Lahore in Pakistan have developed a solar cell based on an absorber made with a lead-free perovskite material known as Cs2AgBiBr6. The novelty of their approach consisted of doping the material with polyacetylene (PA), which is one of the most promising organic polymers for applications in optoelectronics. ...Den vollständigen Artikel lesen ...
