Heliatek, a German specialist in solar energy, announced it set a new record for conversion of organic solar cells of about 12%.

This world record, done in cooperation with German universities of Ulm and TU Dresden, was measured by the accreditation body testing facility (SGS). The measurement campaign was also validated high performance organic photovoltaic cells (OPV) compared to traditional technologies with low light and high temperatures.

The conversion rate of 12% obtained in a standard size of 1.1 cm2, actually combines two absorbent materials – Patented – that convert light on different wavelengths. Indeed, the use of two different sorbents generates a stronger recovery photons and greatly improves energy recovery through a higher photovoltage signal.

Thanks to a unique behavior of OPV at high temperatures and low light conditions, the efficiency of 12% is comparable to the 14% or 15% obtained in the traditional solar energy technologies such as crystalline silicon and thin film photovoltaics. Whereas these technologies lose their effectiveness significantly with an increase in temperature and a decrease in solar radiation, organic cells increase their effectiveness in these conditions leading to energy recovery much higher in real environments.

“We are proud to lead the industry OPV to this historic achievement. Our steady progress reinforces our commitment to achieving an efficiency of 15% by 2015 and gradually transfer the rate of production lines (Heliatek) , roll-to-roll (printed by rotary). We make movies solar and non solar panels. Customers are in the industry of construction materials, automotive and light structures.’s nurseries and the Examples include furniture by such films as solar energy recovery components in order to increase their functionality,” commented The Séguillon Thibaud, a French, CEO of Heliatek.

“Reaching an efficiency OPV unprecedented 12% is a clear validation of the choice of Heliatek not focus on imprinted polymers but to go to oligomers vacuum deposited. This technology has been used Success for OLEDs during the last decade. vacuum deposition enables the design of extremely thin homogeneous layers, up to 5 nanometers (nm) – Only one ten thousandth of a human hair or twice the size of a strand of human DNA. process with this ultra-thin film, we are able to introduce a large number of layers on top of each cell in tandem or even triple junctions to absorb a broader spectrum of light “added Professor Martin Pfeiffer, co-founder of Heliatek.

This new world record efficiency for organic semiconductor materials improves the previous Heliatek also realized there are only 9 months, with a rate of 10.7% .
