Consortium to develop basis for innovative and efficient solar cells
Aixtron announces the formal launch of the research project PeroBOOST on perovskite solar cells together with partners. The basis for this three-year project (03/2016-02/2019) is the recent discovery of the properties of organo-perovskite materials for efficient solar cells. The research projects aims to exploit this class of materials as it offers great potential in terms of its energy conversion efficiency. The latest research perovskite solar cells have already report efficiency levels of more than 20%.
The aim of the project is to investigate the stability of the solar cells and to develop processes and materials to enhance stability. For initial applications, the project aims to achieve a lifetime of 3 to 5 years.
According to the announcement these new type of solar cells are expected to achieve a high level of energy efficiency similar silicon solar cells, expected to be lower costs, In addition, this technology can be made on flexible substrates opening up possibilities for many novel applications. Combining the technology with silicon photovoltaics to further enhance efficiency is another route to market that is very attractive.
According to the Aixtron the perovskite solar cell based on thin film technology has many features in common with innovative organic photovoltaics in terms of the materials used. The disadvantage of perovskite solar cells to date, however, has been that the highest efficiency rates have only been achieved with lead-based materials. The development of perovskite solar cells that are stable on a long-term basis is still in its infancy. Lead-free systems currently show lower levels of efficiency and long-term stability.
The PeroBOOST project will focus on two aspects and aiming to develop these further:
- Efficient and stable lead-free perovskite solar cells
- Scaling up methods and techniques
The project will investigate and develop two industrial production processes, namely vacuum coating and solution-processible roll-to-roll coating.
PeroBOOST is being supported with funds from the European Regional Development Fund (ERDF) 2014-2020.
The PeroBOOST research partners are:
- University of Cologne
- Enerthing GmbH
- Lunovu GmbH
- Soluxx GmbH
- The Center for Organic Electronics Cologne (ZOEK) GmbH
- The Fraunhofer ISE Laboratory and Service Center Gelsenkirchen
- Duisburg-Essen University

About University of Cologne
As part of the "Excellence Initiative", the University of Cologne is supporting the field of "Quantum Matters and Materials (QM²)". This also involves performing basic research on the properties of application-oriented, nanostructured materials. The working group led by Professor Meerholz – also part of QM² – is developing and characterizing new materials and processes for use in the production of efficient (opto-)electronic components with organic semiconductors. A team of around 30 scientists and doctoral students from the fields of physical chemistry, organic chemistry, solid-state physics, and electronics is accompanying this innovation process on an interdisciplinary basis and thus pursuing basic research without losing sight of potential applications. The Meerholz working group is one of the world’s leading groups in the field of organic electronics such as organic solar cells or organic LEDs.

Ever larger numbers of things in our surrounding environment require a supply of electricity. Smartly connecting these things – in the Internet of Things – is expected to lead to further substantial growth. Due to a lack of alternatives, service-intensive batteries and/or complicated cabling are the prevalent solutions.
Enerthing GmbH develops system solutions for the self-sufficient solar operation of existing and new products. The primary objectives are to reduce operating and installation costs and to improve sustainability. Our development of third-generation flexible thin-film photovoltaics modules enables us to combine properties such as excellent low-light performance, low weight, and great mechanical flexibility, thus creating the basis needed for the integration and functionality of new products.
LUNOVU is an innovative laser technology company based in Herzogenrath. The company builds laser machine systems for processing materials, and especially for generative manufacturing and for micro-processing/thin film technology. Its key focus is on integrated systems that include the latest beam sources, optics, select electro-mechanical components and innovative control and automation technology. LUNOVU technology is successfully used in the fields of automotive, aerospace, energy generation, biotechnology, and medical technology.
Founded in Cologne in 2008, Soluxx GmbH is a research and development company focusing on organic electronics. The company’s team has all-round competence and longstanding experience in the fields of materials, coating, measuring technology, and component fabrication.
Soluxx has produced electrospray coating systems for several years now. The company offers both small-scale systems with single sprayers (singleESD) for use in basic research and flexibly scalable systems with multiple sprayers (multiESD) for largescale industrial coating assignments. The benefit of electrospray coating lies in the production of ultrathin, homogenous layers in which the properties of the layer can easily be influenced.
Soluxx is also involved in building precision-mechanical special constructions, such as measuring apparatus, specimen holders, and demonstrators. These activities were supplemented in 2015 by a new business field involving the construction of OLED luminaires. Here, the company produces both large-scale installations with more than 100 individual OLED panels as well as individual lights for consumer applications.
About Center for Organic Electronics (Zoek)
The "Center for Organic Electronics Cologne – Zoek" is a non-profit limited liability company that has set itself the task of building a bridge between application-oriented research at universities and upstream development work at companies and thus of facilitating the “genuine” transfer of research findings. New insights and processes evolving in university environments are developed further to the point at which they can be taken over by industry. The Center's longstanding experience in organic electronics has already made it a specialist in this field. Its core competences are in characterizing electronic-functional materials, implementing organic electronics R&D assignments, and analyzing degradation processes in organic electronic components. The Zoekis the anchor tenant at the "COPT.CENTRE" for Organic Electronics at the University of Cologne. When performing tasks in this project, the Zoek will be drawing on the infrastructure available at the "COPT.CENTRE."
