Heliatek sets new Organic Photovoltaic world record efficiency of 13.2%

15.02.2016 | Heliatek | www.heliatek.com

Heliatek reached a record conversion efficiency of 13.2% for an OPV multi-junction cell, setting a new world record for the direct conversion of sunlight into electricity using organic photovoltaic cells.

Thanks to the excellent low light and high temperature behavior of the organic semiconductor, the electricity generation of the newly developed cells corresponds to the output of conventional solar cells with 16 to 17% efficiency when both are under real world conditions.

New world record for organic photovoltaic efficiency

This new result confirms the world-leading technology position of Heliatek as demonstrated by its continuous progress from 3% to more than 13% efficiency over the last 10 years. It also supports its roadmap towards 15% efficient organic solar cells. The result further validates Heliatek’s unique technology approach of using vacuum deposition of small molecules on plastic films.

The word record cell is a multi junction cell combining three different absorbers. Each of them is dedicated to efficiently convert green, red or near infrared light of the wavelength range between 450 and 950 nm into electricity. These absorber molecules have been developed and are patented by Heliatek.
