Demonstrators of thermoelectric generators

Thermoelectric generators enable to receive usable electric energy from temperature gradients. When placed between a cold and a warmer surface these generators produce electric energy from the heat flowing through the generator.

Passivation layers for photovoltaics

Economical manufacturing of thin solar cells requires alternative concepts of passivating the cells backsides. The advantage of thin film passiviation using aluminum oxide over conventional passivation using screen printing aluminum paste for thin cells is that they will not bend during following heat treatment processes.
