Demostudio OU in partnership with Innovative-Ink GmbH makes a research of semiconductor inks.

P-type semiconductor inks

CIS (Copper-Indium-Sulfide)
CISe (Copper-Indium-Selenide
CIGS (Copper-Indium-Gallium-Sulfide)
CZTS (Copper-Zinc-Tin-Sulfide)
CZS (Copper-Zinc-Sulfide)

Photovoltaic cells

CIS, CIGS, CISe, CZTS and CZS can be combined with an CdS ink to print low cost solar cells.

This inks allow it to reduce production costs of thin film solar cells because of low material costs and very high production speed.
Non toxic and abundant materials possible
Suitable for applications (photoresistor, diod, sensor technology, photovoltaic, energy storage)

Excellent characteristics

The excellent characteristics of our material give up to 40% more power than a Silicon cell with the same formal efficiency during one day. At very low light intensity in the morning or evening even 400% more power is possible.

Nordic countries and indoor

This sensitivity at low light intensity it makes such solar cells interesting for Nordic countries and also for indoor applications. Another big advantage of our printed cells is the high flexibility of the substrate that allows to make building integrated designs.
