Flexible transparent electrode company MSWay said on Thursday that it has developed a high efficiency large-surface flexible organic solar cell electrode.

The electrode, developed together with Gwangju Institute of Science and Technology, is sized 672 centimeter-square and had a photoelectric conversion efficiency of 7.67%.

The US National Renewable Energy Laboratory certifies solar cells that are at least 200 centimeter-square in size. Bigger and wider module poses a challenge in efficiency due to the increase resistance. 

MSWay said 7.67% was the “world’s best” so far in terms of efficiency, saying a local university recorded 5.25% on 107 centimeter-square module. Another German company succeeded in 4.2% efficiency on a 33.5 centimeter-square sized module, the company claimed.

The company’s electrode module was a result of 4 years of collaboration with the Gwangju Institute from the pair’s joint projects on the developments of fullerene for organic photovoltaics (OPV) cells and the large-surface organic solar cell module.

MSWay was also close to the development of a perovskite-based solar cell electrode, which will go into production, the company also said.

Perovskite requires a special protective layer to avoid damages from iodine. MSWay has succeeded in developing the layer, the company said.

The firm received patents related to transparent electrode from the Gwangju Institute in 2016. It has been focusing on roll-to-roll manufacturing of electrodes with over 1 meters in width. It is hoping to list next year.
