German enterprises to break the organic solar cell efficiency world record


The world's leading organic thin-film solar technology German the Heliatek company, recently announced the organic solar cell efficiency and a new world record high, reaching 12%, thus breaking the record of 10.7% of the Company was founded nine months ago. New efficiency has been a professional certification testing organizations.

The battery to achieve a new record 1.1cm2 standard size, the absorbent material containing two Related Patent, they may be in the different wavelength bands to convert light into electricity. Through the combination of two absorber can light with a higher voltage to improve the absorption of a photon, better use of energy.

As The organic photovoltaic unique performance at high temperatures and low radiation efficiency of 12% is comparable with conventional crystalline silicon modules and thin-film photovoltaic cell efficiency of 14-15%. The test results confirmed that, compared to traditional solar panel technology, organic photovoltaic efficiency beyond the average level in low-light and high temperature.

The results showed the the Heliatek company's development strategy, focus on the vacuum deposition of oligomeric absorbent material, rather than printed polymer.The former has been used successfully in the past 10 years in the OLED-display.Vacuum deposition allows thin homogeneous layer settlement, the thinnest only a 5nm thick. The thin layer deposition process, the use of easily grasp a certain number of stacked together, the production of very wide spectral absorption capacity of a laminate battery, or even triple-junction solar cell.

The efficiency of organic solar cell new record is a joint development of the results of the the Heliatek company research team in Dresden, Germany, and the University of Ulm, the R & D program has been funded by the departments and agencies of the German Federal Department of Research, the European Union, the German Association for the Study of . For this achievement, Heliatek plan to the conversion efficiency to 15% by 2015.

The organic solar cell technology based on small molecules (oligomers) has been in the commercial production conversion, the first production line was completed in the spring of 2012, mainly produces solar charge controller film, provide to the building materials, automotive and other industry partners, for the semi-finished products to be used as a component of the capacity expansion of the functions of its own products.Expected integrated Heliatek organic solar film products to enter the market in late 2013. The company plans to continue to invest to build large-scale production lines, to achieve mass production, in order to significantly reduce production costs.
