The Nano-Tandem project is a Research and Innovation Action among six partners, financed by the EC Horizon 2020 Program. The project has started in May 2015 and will continue until April 2019. The main goal of the project is to presents a path for significant performance improvements of photovoltaic modules.
Starting from today’s silicon PV technology, the Nano-Tandem technology promises to increase the efficiency through integration of nanowires on the silicon platform. Ideally this technology offers to reach efficiencies even up to 50 %.
Efficiency improvements of solar cells achieved by Nano-Tandem are a key enabler for European competitiveness within solar energy harvesting technology.
Efficiency is the most important factor in reducing the cost of solar electricity, as all area related costs are reduced by the overall power output of a PV module. Furthermore, PV modules with higher efficiency allow harvesting more energy from a constrained area, like a roof, and becoming attractive for use in countries with reduced solar flux during wintertime, therefore having a higher value for the customer.
High-tech products like the Nano-Tandem cell will help the European industry to have a unique differentiator compared to silicon PV modules, which have become a commodity product.
This will allow the European industry to compete on the international market by offering higher value products with higher performance. Therefore, the development in the Nano-Tandem project will help the European photovoltaic industry to offer more competitive products and to create employment.
This project provides a decision about the most promising approach on manufacturing technologies for the Nano-Tandem cell with respect to low manufacturing costs, technological challenges and ecological risks.
It can be said that the cost targets are very challenging for any new photovoltaic technology to compete with silicon today. But the Nano-Tandem cell has the advantage of very low material consumption and high efficiency potential, making it a promising technology for achieving these targets.
The project investigates new technologies in the field of nanotechnology, which is regarded as a key enabling technology by the European Commission.
Combining the outstanding expertise of European research centers and start-up companies in the Nano-Tandem project will create new knowledge in this important field.
This project provides attractive opportunities for students.
The students will be offered the opportunity to learn in a European research environment with excellent facilities in the fields of nano-technology and photovoltaics.
