Engineers at the University of New South Wales have developed a new solar cell configuration that has achieved a sunlight-to-electricity conversion efficiency of 34.5% - constituting a new world record.

The record was set using a 28cm² four-junction mini module embedded within a prism, dubbed the ‘Power Cube’.  The project was supported by A$1.4 million in funding from ARENA.

The new result, confirmed by the US National Renewable Energy Laboratory (NREL), is almost 44% better than the previous record, which reached 24% efficiency, but over a larger surface area of 800-cm².
