Raynergy Tek is pleased to announce that their latest developed organic photovoltaics (OPV) donor Polymer [PV5001] which required non-halogen formulation component has achieved world record Power Conversion Efficiency of 11.51% using inverted device architecture, independently certified in Taiwan Enli Tech. Optoelectronic Calibration Lab. on June 15th 2016, an established agency approved under TAF.
To our understanding, this certification results is the highest reported OPV efficiency certified using fully green formulation, in other words, halogen-free formulation component, which is vital for industrials adoption, commented by CTO of Raynergy Tek Dr. Chung-wen Ko. He added that the recent public known certified high PCE of >11% materials are either required chlorinated solvents due to solubility issue or required additives like 1,8- Diiodooctane (DIO), which comprises of halogen to achieve best morphology for high efficiency demonstration. Unlike the others, the high performance PV5001 donor is molecularly designed to have good solubility with excellent molecular packing density to preserve charge transport, made possible by the R&D team who constantly focused on creating new polymer by taking consideration of industrials needs , added by Dr. Chung-wen Ko.
This new result confirms the world-leading technology position of Raynergy Tek as demonstrated by its continuous progress from 10% to more than 11.5% efficiency using fully green ink formulation. Raynergy Tek is truly excited of achieving this remarkable milestone. The active layer of PV5001 is >250nm in film thickness for excellent proccessability, optimized for absorption up to 800nm of visible wavelength and processed at low temperature of 10% in efficiency. The head office is located in Hsinchu, Taiwan, including a kilogram scale materials production facility to accommodate the increasing customers' demands, as well as a solar application prototyping facility to allow us to evaluate our performance materials to bridge the gap from lab to R2R manufacturing line. Overall, our expertise team comprises of highly skilled personnels, among which 70% of them are with Ph.D level in the related OPV field. (i.e. Chemistry, Materials science and device physics). We pledge to be customer orientated with highest commitment level to push the frontier of this technology.
