Company History

The company Crystalsol GmbH, founded in 2008, has its Austrian headquarters in Vienna, where the majority of the research and development activities take place, with the main focus on product development. As well as these activities the finishing is also carried out directly in Austria. The production of the semi-conductor powder takes place in the crystalsol OÜ, Estonia (Tallinn). By now both locations employ 29 people.

Through the intensive collaboration with a number of research partners throughout the whole world (Germany, Estonia, Portugal, Singapore), it has been possible to increase the efficiency of the technology from 1% to almost 10%. The business is currently about to enter the market with its first customers in the BIPV-area (building-integrated photovoltaics).

At the beginning of 2013 the business was able to successfully achieve the first round of funding totalling EUR 8 million and, as a result of this round of financing, won some very important investors and partners.

At the end of 2014 Crystalsol also received support from the climate and energy fund, totalling EUR 3.2 million, for the further development of the technology.

Next Steps

  • 2015: Market entry with test customers middle of the year
  • 2015/16: Optimisation of the technology for use in the BIPV-area as well as cost-effective set-up of the production process
  • 2017: Large scale production through a production partner

In the long term an efficiency rate of 20 % (with a theoretical maximum value of 34 %) should be achieved for the sheets.
