Home Made Solar Cell

The solar guys from TU Berlin had the chance to visit the Helmholtz-Zentrum Berlin, in this center we had also the chance to build our own solar cell... I was something really interesting, because you do not need a lot of materials to build it... of course the efficiency is about 0.3% jajaja, but anyway it was fun.

After building several cells we could power a pocket calculator, this proves that you do not need to go to the big factories to learn about technology... this center is a very good example of hard work brought to simple people...

and because we are all foreigners we played with the snow in Wansee... it was fun also....
