ISC Konstanz e.V.: For a sunny future.

What does ISC Konstanz stand for?

Since its founding in 2005, ISC Konstanz has been pursuing one goal as a non-profit associa-tion: advancing the energy transition. To this end, we research and develop highly efficient solar cells, modules and systems for industrial production. we are committed to the cause, not to profit. Then and today.

That is why ISC Konstanz needs your help.

In order to meet the increasing demand for optimized photovoltaic solutions, ISC Konstanz is planning an extension to the research center. We want to drive solar energy research in Germany forward unabated – but to do so, we need your help! After funding from the feder-al and state governments, we still need donations of 4 million euros. Please support us with your donation to make the energy transition a reality.

Donate property

We build the place where a livable tomorrow is created today:

To ensure that ongoing operations can continue uninterrupted during the construction work, a new building is planned on the neighboring property of the ISC Konstanz. Donate to purchase the land and build a new, fully functional and modern research center so that we can continue to work on strengthening Germany as a solar location and stopping climate change. For example, with 1,000 euros you finance a symbolic square meter of the new property.

Every contribution is valuable and brings us a little closer to our common goal.

Donate new building

We are building the place where the energy transition is becoming reality:

Good research needs good conditions. And we definitely want to create these with the ex-pansion of our research center. Join us in building and help equip our new building with your donation.

  • If we find 100 people who donate 500 euros each, we will be able to build and equip a new measurement room.
  • 100 donors who give 250 euros each will make one of the new offices possible

With every contribution, we drive the energy transition forward together.

Donate new machines

We are building the place where every step brings progress

Research is not only done on paper. The ISC Konstanz develops highly efficient solar cells, modules and systems for industrial production. To strengthen Germany as a solar location, we want to deliver the best photovoltaic solutions. With your donation, you help the ISC Konstanz to purchase necessary machines and thus drive progress.

Your machine donation is a decisive contribution to our common goal.

Why is the project not financed by the federal and/or state government?

We are not a public institute or university, so we do not receive basic funding from the public sector. However, the big advantage is our independence: we can act quickly and be-nefit from lean structures and uncomplicated decision-making processes. In a sense, we are the “speedboat” in solar energy research – which is why we are able to actually turn our in-dustry-oriented research into production. We also receive public funding to a limited extent – but it is project-related and therefore cannot be used for a new building or for the main-tenance and equipping of buildings.

Why can't the project be financed from the ISC's business activities?

Our business model is successful and has stood the test of time for 17 years, through all cri-ses. We cannot manage a project as large as the new construction of the ISC research cen-ter on our own, despite the stable foundations – not at the speed that is now necessary in the energy transition. We are investing in the future and in the livelihood of future genera-tions. This is such a large and important project that we need “co-investors” to shoulder it with us.

We are competing with institutes that are publicly funded – including the buildings they use. If we raise our prices too much to make the new research center financially possible, our prices will no longer be competitive with those of our competitors.

Why is solar research important in Germany?

The energy turnaround decided by politicians and important for achieving the 1.5 degree target is based on the massive conversion from fossil to sustainable energy sources, which also include solar energy. Photovoltaics, as the world’s cheapest source of energy, is very li-kely to attract more attention from politicians and society in the next few years. In parallel, technology imports from China are coming under increasing criticism for strategic and ethi-cal reasons. Last but not least, the dependence on Russia is leading to a rethinking in Ger-many towards the desire to make its own energy production as self-sufficient as possible.

Why is land so expensive?

In Constance, prices are generally rather high. However, it makes a lot of sense and is very efficient to build the new research center directly on the existing site. This way, the ISC avoids an interruption of operations, which would probably cause more costs and reduce the necessary project speed.
