Was bedeutet Heterojunction? Die HJT-Solarzelle ist eine Kombination aus einem kristallinen Silizium-Wafer und einer Dünnschichtzelle aus amorphem Silizium. Während in normalen Solarzellen das gleiche Halbleitermaterial unterschiedlich dotiert wird, um einen pn-Übergang zu erzeugen, entsteht dieser bei der HJT-Solarzelle zwischen zwei unterschiedlichen …
It is very necessary to design a high-capacity and stable Bi 2 O 3 anode for nickel-bismuth (Ni//Bi) batteries. In this work, a stable α- and β- phase Bi 2 O 3 heterojunction nanocomposite (α/β - Bi 2 O 3) was successfully prepared via a simple "space-confined" strategy and it was used as a superior anode for nickel-bismuth (Ni//Bi) battery.
