Solliance sets 12.6% efficiency record for roll-to-roll perovskites

March 10 (Renewables Now) - Solliance has set a world record by achieving a stabilised efficiency of 12.6% for roll-to-roll produced perovskite solar cells, it announced on Thursday.

The research consortium, which groups organisations from the Netherlands, Belgium and Germany, has demonstrated an industrially-applicable roll-to-roll process for the production of solar cells, with individual cells of 0.1 sq cm  (0.0155 sq inch) showing efficiencies of up to 12.6%, measured under maximum power point tracking conditions during 5 minutes.

According to Solliance the achievement could help speed up the market introduction of the promising perovskite photovoltaic (PV) technology.

The roll-to-roll process used low-cost materials and was carried out at temperatures below 120 degrees C, which, Solliance said, demonstrates the high-volume production potential of the technology. "The demonstration of R2R processing at 5 m/min of perovskite layers for solar cells indicates that high-volume production, and hence with an expected very low cost, will be possible in the future," said Pim Groen of the Technical University of Delft.

Currently, the world record efficiency of a small lab scale perovskite cell is 22.1%.

"The challenge is to upscale perovskite cells to larger size, industrially-manufacturable modules with high efficiency and long lifetime at low cost," said Ronn Andriessen, programme director at Solliance. "These 12,6% R2R up-scaled perovskite-based solar cells are a first and important step in this development," Andriessen added.   

Solliance's industrial partners on perovskite research are Solartek, Dyesol Ltd (ASX:DYE) and Panasonic Corp (TYO:6752).
