Research for a sunny future!

Publicly funded research projects enable the ISC to try new approaches with its partners. Usually together with industrial partners, projects are carried out that should lead to commercialisation within a period of two to three years. During this period, for example, manufacturing processes for new types of solar cells or modules can be researched, and developments for new machines can be tested.
We are currently working in serveral publicly funded projects with about 50 industry partners and 34 institute partners and cooperate with many research institutions. We have 17 years of experience in applying for and implementing projects in various funding programmes:

  • Federal Ministry for Economic Affairs and Climate Action(BMWK): 7th Energy Research Programme of the Federal Government
  • Federal Ministry for Economic Affairs and Climate Action(BMWK): Central Innovation Programme for SMEs (ZIM)
  • Federal Ministry of Labour and Social Affairs (BMAS): Establishment of continuing education networks
  • Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU): AI lighthouse projects for the environment, climate, nature and resources
  • Ministry of Economics, Labour and Housing Baden-Württemberg: Funding programmes of the state of Baden-Württemberg
  • EU-funded research (Horizon 2020 and now Horizon Europe)
  • various other international funding programmes

We are happy to support you in the development of joint project ideas and funding applications and to network you with other partners. So that ideas can become products!

vtb – Verbund für Technologie und Bildung Bodensee-Oberschwaben

Funding source: BMAS
Funding code: WBV.02.00001.22 – WBV.02 – Weiterbildungsverbünde Fahrzeugindustrie
Term: 01.03.2022 – 31.12.2024
Budget of the ISC Konstanz: 427.998 €
128.399 € own funds 30%
299.598 € donation 70%
Topic: The Lake Constance-Upper Swabia region is characterized by vehicle construction. Numerous small and medium-sized companies shape the supplier landscape with two top companies in the field of drive and chassis technology. Through these activities in hybrid and electric drives associated vehicle electronics and software applications are increasing. In addition to three manufacturers/fitters of motorhomes, the area of commercial and special vehicles is important. The speed of change of existing professional fields in the automotive industry (AMI) is currently being felt particularly strongly. The transformation described in the call for proposals requires new skills and also abilities of the people who have worked in the AMI so far, so that their companies remain sustainable, but also to continue to provide these skilled workers to stay in the labor market. The peculiarity of the region is that on the one hand, many AMI companies are affected by digitalization, new technologies and changing customer wishes faced with the challenges of a structural change, while companies in other sectors (Aerospace, pharmaceutical and electronics industry, nursing professions) are on a growth path. Many of the companies in the growth sectors are faced with the challenge of an increasing shortage of skilled workers. According to this double structural challenge in the region, the consortium has set itself the goal of this project application, on the one hand AMI employees for the challenges and professional fields of the future to qualify. What is needed here is not just new professional qualifications, but also comprehensive competencies, such ones as based on technological knowledge, creativity in thinking and acting, the ability to be open for lifelong learning and cooperate with other companies on an equal footing. In focus is to sensitize companies and employees to the opportunities that exist and arise through targeted further qualification. On the other hand, the training network vtb will further create new perspectives where positions are under strong substitution pressure, open up new opportunities for people through a transfer to growth sectors is prepared as well. This avoids a brain drain from the region and at the same time employees who are currently exposed to a threat to their jobs, are given the perspective that their skills will continue to be available on the job market can be useful.

PV Mobil - Development of an integrated photovoltaic storage module

 

Funding source: BW Invest
Funding code: BW1_2114/03
Term: 01.12.2022-30.11.2024
Budget of the ISC Konstanz: 114.000€
Topic: An integrated photovoltaic storage module is to be developed that can supply electrical energy at any time of the day or night. Compared to the procurement of the individual components, the element should be much cheaper to produce. All applications in which a photovoltaic module and an electrical storage unit are installed in close proximity to each other can benefit from the result, in particular applications in very small vehicles (e.g. senior citizens’ mobile homes and boats) but also stationary applications such as so-called balcony modules. Optionally, the storage module should also be able to be charged with electricity from the public grid or another power source (e.g. fuel cell).

LOGIC - Low cost high efficiency Cu plated IBC - low cost and high efficiency back-contact solar cells with galvanic copper contacts

 

Funding source: BW Invest
Funding code: BW1_4206/02
Term: 01.06.2023 – 31.05.2023
Budget of the ISC Konstanz: 400.000€
Topic: Silver is the only scarce resource when scaling the solar industry to much higher production volumes. However, such scaling is imperative to achieve our climate goals. PV2+’s copper technology has the potential to completely eliminate silver from solar cell manufacturing. In the LOGIC project, the copper technology of PV2+ is to be combined with the advanced, highly efficient ZEBRA back-contact solar cell of ISC Konstanz. This should result in a solar cell that has the highest efficiency potential, can be produced cost-effectively and relies only readily available raw materials, thus representing the next logical step on our roadmap to sustainable photovoltaics.
