Wie funktioniert eine Heterojunction-Solarzelle?
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 …
