Solliance Achieves R2R Perovskite Solar Cells and Modules

Solliance has achieved world record cell-level conversion efficiency of 13.5% and module-level aperture area conversion efficiency of 12.2% for perovskite-based photovoltaics using industrially-applicable, roll-to-roll (R2R) production processes.
                       
Perovskites, are perhaps, the most exciting solar energy technology to appear in recent years. They offer high efficiency from relatively simple production processes, bringing the potential for cheaper, greener energy. Moreover, they can be processed into thin, lightweight and potentially semi-transparent modules for integration into windows or curved construction elements.
 
Solliance and its partners are helping to speed the market introduction of this technology by developing scalable, industrial processes for fabricating large-area modules.
 
All processing steps used low-cost materials and scalable processes at temperatures below 120 °C. This highlights the potential for cost-effective, high-volume production of perovskite solar cells.
 
“These results show that the developed R2R process is very reproducible over different runs in time, which is very important for future reliable manufacturability,” said Pim Groen, professor of SMART materials at the Technical University of Delft and program manager at Holst Centre/Solliance.
 
“The metals project at Solliance is hitting its targets,” added Richard Caldwell, managing director of Greatcell Solar. “The successful translation of this PSC technology from the laboratory to the factory will open up massive commercial opportunities.”
 
Solliance reported that it is confident of quickly boosting efficiencies above 15% for modules up to 30×30 cm2. Solliance’s research on the development and applications of perovskite-based PV modules is carried out in conjunction with industrial partners Greatcell Solar Limited, Solartek and Panasonic.
