The 4cm x 4cm perovskite solar cell achieved 12.4% power conversion efficiency under more than ten minutes maximum power point tracking as certified by Fraunhofer ISE
Imec and partner Solliance have announced that they have improved their 4 cm x 4 cm perovskite module and achieved a certified conversion efficiency of 12.4%,
which the researchers believe is amongst the highest for this size of perovskite modules.
The module efficiency was measured under long-term maximum power point (MPP) tracking, testifying to its exceptional stability. According to Solliance this perovskite technology is developed using industrially-applicable processes with a view towards a fast market introduction of this promising source of renewable energy.
The state-of-the-art perovskite modules were made at imec using an advanced recipe for the active
layer and a process that achieves a very high aperture area efficiency in combination with a high
operational device stability.
In the current design, eight cells are connected in series by using a low
area loss interconnection technology based on laser and mechanical patterning. Due to this
optimisation, about 90% of the designated illumination area of 16 cm2 is contributing to the energy

The device stability and performance is represented by the 12.4% power conversion efficiency under more than ten minutes maximum power point tracking as certified by Fraunhofer ISE.
Imec develops its industrial R&D platform for perovskite modules in the framework of Solliance, a cross-border Dutch-German-Flemish thin-film photovoltaics research initiative, conducting advanced research on the development of perovskite-based PV modules and its applications, with industrial partners Solartek, Dyesol and Panasonic.
Tom Aernouts, Solliance program manager and group leader for thin-film photovoltaics at imec, said, "This breakthrough achievement confirms that we are able to steadily improve the conversion efficiency of perovskite solar modules." Tom added, "In a few years’ time, we have made rapid progress not only on conversion efficiencies for single cells but are now also consolidating this at module level for this type of thin-film photovoltaics. Looking ahead, within Solliance we’ve set an aggressive roadmap for larger-area low cost processing and long-term stability that will advance this technology beyond the lab."
Denis Kovalevich, The Chair of the Board of Directors of Solartek, said, "Solartek is excited with this breakthrough; we are going to continue our fruitful collaboration with Solliance, supplying imec and other research teams with samples of high tech materials, such a CNT inks, to reduce the cost of production of perovskite modules on large scale processing by replacing most expensive materials, like gold."
Perovskite microcrystals are a promising material to make high-yielding thin-film solar cells. They can be processed into thin, light-weight, semitransparent modules that could eventually be integrated in building materials such as windows or curved construction elements.
Imec and Solliance focus on using scalable, industrial processes towards the fabrication of large-area modules, eventually suitable for seamless integration in customised PV systems.
