The solar cell was fabricated with a special polymer that is able to passivate defects at the grain boundaries and interfacial surfaces, inhibit nonradiative recombination and charge-transport loss, and improve stabilities under moisture. The device exhibited a remarkable fill factor, of 0.862.Scientists at the Northwestern Polytechnical University in China and the Swiss Federal Institute of Technology, Lausanne (EPFL) have fabricated an inverted perovskite solar cell based on a star-shaped polymer that they claim is able to improve charge transport and inhibit ion migration at the perovskite ...Den vollständigen Artikel lesen ...
