Australian researchers built a perovskite solar cell with guanidinium bromide and octylammonium bromide cations. They claim the device can achieve a higher open-circuit voltage, while exhibiting better efficiency and stability.Australian researchers have developed a perovskite solar cell with a novel passivation process based on the use of guanidinium (Gua) and octylammonium (Oa) spacer cations. They claim that guanidinium salts can improve the performance of the perovskite film, as guanidinium ions are capable of penetrating into the bulk of the perovskite material and localizing at the grain ...Den vollständigen Artikel lesen ...
