Perovskite PV module reaches 12.4% efficiency

Belgian nanotechnology research group Imec this week announced certified conversion efficiency of 12.4% for a 16-sq-cm perovskite solar module, developed with industrially-applicable processes.

Imec, which is part of the Solliance research consortium, said the current design of 4 cm x 4 cm uses eight cells connected in series by using a low area loss interconnection technology based on laser and mechanical patterning. The efficiency it achieved is amongst the highest for this size.

The 12.4% power conversion efficiency has been measured under more than ten minutes maximum power point (MPP) tracking and certified by Fraunhofer Institute for Solar Energy Systems ISE.

“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,” said Tom Aernouts, group leader for thin-film photovoltaics (PV) at Imec and Solliance programme manager.

Solliance has gathered together research organisations from the Netherlands, Belgium and Germany. Solartek, Dyesol (ASX:DYE) and Panasonic (TYO:6752) are industrial partners in the consortium.

Imec will be at the SNEC PV Power Expo in Shanghai next week.
