According to German scientists, the quality of the photoluminescence quantum yield of the perovskite layers can be reliably and precisely determined for the first time. It shows that the promising material has more potential for optimization than previously assumed.From pv magazine Germany Perovskite solar cells can theoretically achieve a power conversion efficiency of around 30.5%. In order to approach these efficiency levels, however, the optoelectronic quality of perovskite semiconductors must increase. In principle, materials suitable for photovoltaics should not only absorb light but also ...Den vollständigen Artikel lesen ...
