Awards ceremony for best project of the past 25 years

The LIFE+ Project allowed for the building of a pilot line which lay the ground work for the design and manufacturing of the complete factory. The EU LIFE+ Programme has been pivotal in the construction of the world’s largest DSC factory.


The overall objective of the project is to demonstrate a cost-effective means of producing DSCs through the construction of a pilot production line.

  • 30% reduction of production costs
  • 50% reduction in embedded energy from production
  • 40% reduction in CO2 emissions in comparison with silicon solar cells
  • 20% reduction in volume of waste produced
  • 50% reduction in investment and operational costs
  • 50% reduction in storage, transportation and handling costs
  • Lower carbon footprint through 50% recyclable production

The pilot production plant is located in the Stockholm city centre.
This pilot plant has been developed with the financial support from the European Commission.

The DSC characteristics are ideal for a variety of real-life conditions. They are less sensitive to the angle of incident light in comparison to other technologies. They have stable efficiencies in all light conditions. They have higher efficiency than competing technologies in higher working temperatures. This makes them ideal for applications where even output is preferable.

Screen printing is a well established, proven and cost efficient production method. A modular design of the factory enables scalability for future plans of setting up large scale manufacturing in target markets.

In 2014 a yearly production capacity of 20,000m2 was demonstrated.
Scalability was confirmed.

The potentially usable radiation of the sun is about 1.9×108 TWh per year which translates to approximately 170 times the total amount of energy of global coal reserves. This means the solar energy reaching the earth’s surface during only 6 hours is enough to meet all global energy needs on an annual basis.

The Dyemond Solar project has proved the production potential and scalability of screen printing as a production method for manufacturing dye sensitized solar cells. This solar technology in combination with the chosen production method is sustainable and environmentally friendly with no toxic emissions, allowing for a pilot plant to be situated in the city centre of Stockholm.
