November 23 (Renewables Now) - Solliance said this week it has achieved record cell-level efficiency of 13.5% and module-level aperture area efficiency of 12.2% for perovskite-based photovoltaics (PV) using industrially-applicable, roll-to-roll (R2R) production processes.

The Dutch-Flemish-German thin-film solar research consortium also expressed confidence of quickly increasing efficiencies above 15% for modules up to 30x30 sq cm (4.65 sq inch).

The new world records come after Solliance in March achieved 12.6% conversion efficiency on cell level. The consortium is working to accelerate the market introduction of the perovskite technology by developing scalable, industrial processes for manufacturing large-area modules. Its latest achievement includes maximum aperture stabilised efficiency of 12.1% for 4 sq cm modules, of 12.2% for 10.5 sq cm modules and 10.1% for a large module of 160 sq cm.   

Ronn Andriessen, program director at Solliance, explains that perovskites have shown very high efficiencies in lab-scale PV cells and the challenge now is to upscale cells to larger modules with high efficiency and long lifetime at low cost. Andriessen added Solliance is excellently placed to realise the upscaling, while its research shows that optimising materials and processes is steadily improving the stability of perovskite devices under real life operational conditions.

"A particularly pleasing feature of the current progress is the possibility to solar enable commercial and industrial roofing using low-cost R2R processes, thus opening up a whole new space to capture the Sun’s energy, all day, every day," said Richard Caldwell, managing director of Greatcell Solar (ASX:GSL), one of Solliance's industrial partners.
