Heliatek pushes organic solar cell efficiency higher #solar #green

LONDON – Heliatek GmbH (Dresden, Germany), a startup developing organic solar cells, has pushed the record efficiency for organic solar cells higher, achieving an efficiency of 10.7 percent in a 1.1 square centimeter tandem cell. The efficiency was measured by indepdendent test house SGS SA (Geneva Switzerland). Heliatek, founded in 2006 as a spin off from the universities of Desden and Ulm, is based on the use of small organic molecules to produce highly tailorable, low temperature, low cost organic photovoltaics, which although less optically efficient than silicon could prove to be more economically efficient. SGS measurements included showed that the cell has improved efficiency under low light conditions and that the efficiency remains constant with temperature. Heliatek is currently working on its first roll-to-roll manufacturing line installed in Dresden, Germany, t...
