Research continues in the field of perovskite technology, particularly in tandem applications. While the efficiency achieved in the latest published work in the field has only achieved 13.8% efficiency, MIT-Stanford researchers say that the voltage of 1.65 V was at the top of the range the team had set as a target. Key to the achievement, report the solar researchers is the effective tunnel junction achieved in the perovskite-cSi cell. The team used degenerately doped p-type and n-type silicon for the tunnel junction. A titanium-dioxide layer is also used ...Den vollständigen Artikel lesen ...
