Australian engineers have set a new solar energy world record

Australian engineers have edged closer to the theoretical limits of sunlight-to-electricity conversion by photovoltaic cells with a device that sets a new world efficiency record. A new solar cell configuration developed by engineers at the University of New South Wales has pushed sunlight-to-electricity conversion efficiency to 34.5% – establishing a new world record for unfocused sunlight and nudging closer to the theoretical limits for such a device. Previous record was 24%.
