Solliance is a partnership of R&D organizations from the Netherlands, Belgium and Germany working in thin film photovoltaic solar energy. Aiming to strengthen the EU region’s position as a world player in PV, Solliance is creating synergy by consolidating and coordinating the activities of 250 researchers in industry, at research institutes and universities.
Various state-of-the-art laboratories and pilot production lines are jointly used for dedicated research programs which are executed in close cooperation with the solar business community.
Among Solliance Research Partners are: ECN, imec, TNO, Holst Centre, TU/e, Forschungszentrum Jülich, University Hasselt and Delft University of Technology.
Solliance offers participation in its research programs and opens up its lab facilities to new entrants, either from industry or in research. On the basis of clear Intellectual Property agreements, each industrial partner can participate in this research effort, or alternatively, hire equipment and experts to further develop its own technology.
The latest Solliance news:
Solliance partners TNO, imec/EnergyVille and the Eindhoven University of Technology, have reported a 18.6% efficient highly near infrared transparent perovskite solar cell. When combined in a four terminal tandem configuration with an efficient Panasonic crystalline silicon (c-Si) cell or with a Miasolé flexible CIGS cell, the configuration delivered new record power conversion efficiencies of 28.7% and 27.0%, respectively.
The researchers explained that four terminal tandems allow to build on experience and practices already available in the industry. In addition, four terminal perovskite/c-Si tandems can be applied broadly and are, for example, very beneficial in combination with bifacial c-Si solar cells which, depending on the actual albedo, can readily achieve a total power generation density as high as 320 W/m².
Flexible semi-transparent tandem perovskite/CIGS solar cell with 26.5% efficiency reported by Solliance and MiaSolé
Solliance and U.S-based MiaSolé announced a new record - power conversion efficiency of 26.5% on a tandem solar cell that combined a top rigid semi-transparent perovskite solar cell with a bottom flexible copper indium gallium selenide (CIGS) cell.
This impressive efficiency was achieved by optimizing the bandgap and the efficiency of both the rigid semi-transparent perovskite top cell and the flexible CIGS bottom cell. The CIGS was roll to roll produced on steel foil, with a power conversion efficiency of 20.0%.
Scientists from Hasselt University, imec, VITO, EnergyVille and international partners within the PERCISTAND consortium have announced that they achieved an energy efficiency of 25% with a thin-film solar cell.
Bart Vermang, coordinator within the PERCISTAND consortium, describes the development of thin-film solar cells as ‘Pioneering’. The consortium, which partly consists of the collaborations within EnergyVille and Solliance, has succeeded in achieving a record energy efficiency with thin film solar cells. ‘We’ve achieved an energy efficiency of 25 percent for the first time, which is just as much energy as a traditional solar cell can generate on a day-to-day basis. And we haven’t yet reached the upper limit of our thin-film solar cells.’
In what is said to be a "major milestone toward commercialization", Solliance partners TNO, imec and the Eindhoven University of Technology demonstrated encapsulated perovskite solar modules fabricated using industrial processes that withstand three established lifetime tests, i.e. the light soak test, the damp-heat test and the thermal cycling test. It is for the first time this milestone is passed with scaled perovskite solar modules prepared by research organizations.
The efficiency and versatility of perovskite solar modules has generated a lot of interest in this novel solar energy technology. However, concerns have been raised about the stability of perovskite solar modules since the early devices, reported a decade ago, were only stable for minutes. By passing three rigorous aging tests, Solliance and its industrial partners take a major step towards commercialization of this novel solar technology.
For the purpose of decarbonizing the energy-mix, which is becoming a priority challenge for European countries among others, European universities, research institutes and industries involved in the development of perovskite technologies have agreed on the creation of a collaborative platform: the EPKI.
This initiative is dedicated to gathering all significant parties working in this field and is pursuing the following objectives:
- Raise the awareness on perovskite based photovoltaics by conveying a common vision through the editing of a common European perovskite whitepaper,
- Support and initiate next generation PV industrial initiatives,
- Facilitate joint-research programs and synergies among universities, institutes and companies.
