Hibiskusblütenfarbstoffsolarzelle
Am Donnerstag, den 1. Dezember 2011 war der Science on Tour- Bus wieder einmal in der Schule und mit ihm Herr Krätzschmar von der Fachhochschule Lausitz. Diesmal durften die beiden Chemie-Grundkurse der Q-Klassen zum Thema „Die Farbstoffsolarzelle“ experimentieren.
Nach einer kurzen Einführung in das Thema tüftelten wir jeweils zu zweit an den Gerätschaften und Chemikalien und bauten uns in 3 Stunden nach einer Anleitung eigene kleine Solarzellen mit Hibiskusblütenfarbstoff. Herr Krätzschmar, Frau Mantwill und Frau Wolfgramm hatten alles im Griff und so gab es, trotz kleinerer Missgeschicke zum Glück keine größeren Explosionen.
Am Ende konnten unsere Solarzellen, durch Lampen angeregt, sogar richtigen Strom erzeugen!
Eine wirklich gelungene Ablenkung zum oftmals komplizierten Chemieunterricht! Alle Schüler hatten großen Spaß und der Science on Tour-Bus konnte mit viel Lob im Gepäck wieder zur Fachhochschule zurück fahren! Danke an die Chemielehrer und alle Verantwortlichen!
