Bessere Solarzellen durch Weltraumexperimente

(PresseBox) (Erlangen, )
Um den Partikeleinbau bei der Züchtung von Siliziumkristallen für die Photovoltaik besser zu verstehen, bereiten Forscher vom Fraunhofer IISB in Erlangen gerade das Weltraumexperiment ParSiWal vor. Das Experiment soll klären, durch welche Mechanismen für die Materialeigenschaften nachteilige Siliziumkarbid-Partikel bei der Kristallisation in den Siliziumkristall eingebaut werden. Das Experiment wird 2013 auf der deutschen Forschungsrakete TEXUS 51 stattfinden - genau 30 Jahre nach dem ersten Erlanger Weltraumexperiment, das 1983 vom Wissenschaftsastronauten Ulf Merbold auf dem Space Shuttle während der 1. Spacelab-Mission durchgeführt wurde.

Bei der industriellen Produktion von multikristallinen Siliziumblöcken für die Photovoltaik spielen Partikel in Form von Siliziumkarbid (SiC) eine lfxrn Tctss.
